00:01.350 --> 00:02.530
- [Instructor] This
video is brought to you

00:02.530 --> 00:05.050
by the Program Manager,
Infantry Combat Equipment,

00:05.050 --> 00:06.420
or PM ICE.

00:06.420 --> 00:08.240
PM ICE is a program management office

00:08.240 --> 00:09.630
within Marine Corps Systems Command,

00:09.630 --> 00:11.410
located in Quantico, Virginia.

00:11.410 --> 00:13.440
This video is one in a series of videos

00:13.440 --> 00:15.980
PM ICE has developed in order to instruct,

00:15.980 --> 00:19.040
educate, and assist
Marines in the proper form,

00:19.040 --> 00:21.820
fit, function, use, and care

00:21.820 --> 00:23.870
of infantry combat equipment being fielded

00:23.870 --> 00:25.760
by this program office.

00:25.760 --> 00:27.810
The purpose of this
video is to demonstrate

00:27.810 --> 00:30.770
the proper use and care of
the Enhanced Combat Helmet,

00:30.770 --> 00:33.400
referred to from hereon as the ECH.

00:33.400 --> 00:37.170
Please note that this is an
updated video of the ECH.

00:37.170 --> 00:39.610
An update was needed due to
the new retention system,

00:39.610 --> 00:42.990
as well as the new Night
Vision Device bracket.

00:42.990 --> 00:45.750
Here is the original
ECH with the NVD bracket

00:45.750 --> 00:48.510
and the X-back retention system.

00:48.510 --> 00:50.100
If you have this particular helmet,

00:50.100 --> 00:52.150
please watch our original video

00:52.150 --> 00:54.940
on Marine Corps Systems
Command's YouTube channel.

00:54.940 --> 00:57.410
The search title for that video is simply

00:57.410 --> 00:59.453
Enhanced Combat Helmet Training Video.

01:00.510 --> 01:03.640
Here is the ECH that we
will discuss in this video.

01:03.640 --> 01:05.280
There are absolutely no differences

01:05.280 --> 01:07.160
between the actual helmets.

01:07.160 --> 01:11.200
As I mentioned, the only
difference is the NVD bracket

01:11.200 --> 01:14.270
and the new H-back retention system.

01:14.270 --> 01:16.200
If you have this version of the ECH,

01:16.200 --> 01:18.120
then this is the video for you.

01:18.120 --> 01:19.960
It's important to point
out that this helmet

01:19.960 --> 01:21.930
is not replacing this helmet.

01:21.930 --> 01:23.600
Two Marines could be
wearing these two helmets

01:23.600 --> 01:25.770
side by side, and one does not have

01:25.770 --> 01:27.750
any more protection than the other.

01:27.750 --> 01:30.190
The only difference
again is the NVD brackets

01:30.190 --> 01:32.270
and the retention system.

01:32.270 --> 01:33.950
During this video, we will demonstrate

01:33.950 --> 01:37.220
the procedure for inspecting
the ECH for serviceability,

01:37.220 --> 01:41.710
installing the NVD bracket,
the reversible helmet cover,

01:41.710 --> 01:44.130
and the suspension system pads.

01:44.130 --> 01:46.500
We will also cover donning the ECH,

01:46.500 --> 01:49.040
making proper adjustments
to the retention system,

01:49.040 --> 01:51.310
and the care and cleaning of the ECH.

01:51.310 --> 01:53.420
Finally, we will
demonstrate how to determine

01:53.420 --> 01:55.730
an individual Marine's helmet size.

01:55.730 --> 01:58.600
The ECH is a result of an
urgent statement of need

01:58.600 --> 02:00.650
that called for improved
ballistic protection

02:00.650 --> 02:04.050
against select small-arms
ammunition and fragmentation,

02:04.050 --> 02:06.820
while maintaining the weight
of the lightweight helmet.

02:06.820 --> 02:09.820
The ECH was co-developed by
the Marine Corps and the Army.

02:09.820 --> 02:12.340
The ECH will replace the currently-issued

02:12.340 --> 02:14.020
lightweight helmet.

02:14.020 --> 02:17.540
The ECH will be issued out of
the Individual Issue Facility,

02:17.540 --> 02:20.570
and the sizes will range from
small through extra large.

02:20.570 --> 02:22.550
As with all helmets, a properly-sized

02:22.550 --> 02:25.350
and properly-worn helmet
significantly increases

02:25.350 --> 02:27.810
its protection capabilities.

02:27.810 --> 02:30.230
Before we begin, let's
discuss the components

02:30.230 --> 02:32.210
that make up the ECH.

02:32.210 --> 02:34.660
The bare helmet itself
is called the shell.

02:34.660 --> 02:37.763
The outer edges of the shell
are covered by the edge trim.

02:38.840 --> 02:40.700
The components of the ECH include

02:40.700 --> 02:43.330
the new H-back retention system,

02:43.330 --> 02:45.765
a Night Vision Device bracket,

02:45.765 --> 02:49.470
a reversible helmet cover
with the hole precut,

02:49.470 --> 02:52.000
and a set of seven suspension system pads,

02:52.000 --> 02:54.720
which must be installed at all times.

02:54.720 --> 02:57.360
The quantities of the pads are as follows:

02:57.360 --> 03:01.270
one crown pad, four oval pads,

03:01.270 --> 03:03.320
and two front/rear pads.

03:03.320 --> 03:05.630
The standard pads are
3/4 of an inch thick,

03:05.630 --> 03:08.170
however, for those
requiring a more snug fit,

03:08.170 --> 03:10.990
there are also one inch
pads available upon request

03:10.990 --> 03:12.863
via the Individual Issue Facility.

03:13.710 --> 03:15.810
Finally, a quick reference
guide will be issued

03:15.810 --> 03:17.280
with each helmet, which will include

03:17.280 --> 03:19.340
information presented in this video,

03:19.340 --> 03:20.870
as well as additional information

03:20.870 --> 03:22.333
not covered in this video.

03:23.530 --> 03:24.990
We'll now demonstrate the procedures

03:24.990 --> 03:27.610
for inspecting the ECH for serviceability.

03:27.610 --> 03:28.870
You should conduct this inspection

03:28.870 --> 03:32.780
when you first receive the ECH,
and periodically during use.

03:32.780 --> 03:35.880
On the helmet itself,
examine for dents, cuts,

03:35.880 --> 03:37.663
and chipped or delaminating paint.

03:38.640 --> 03:41.060
Next, check the shell's
edge trim for any loose

03:41.060 --> 03:42.253
or missing material.

03:43.470 --> 03:46.524
Inspect for damaged or loose hook disks.

03:46.524 --> 03:48.740
Disks that will not securely
hold the pads in place

03:48.740 --> 03:50.780
will require the wearer
to turn the helmet in

03:50.780 --> 03:51.763
for a replacement.

03:53.010 --> 03:56.820
Next, check the retention system
for torn or frayed webbing,

03:56.820 --> 04:01.573
broken adjustment slides,
serviceable chinstrap,

04:03.520 --> 04:05.763
and missing or loose attaching hardware.

04:11.500 --> 04:14.900
Any of these problems render
the ECH unserviceable.

04:14.900 --> 04:18.490
Finally, inspect the pads for cuts, tears,

04:18.490 --> 04:22.480
or other damaged outer fabric,
deteriorated inner foam,

04:22.480 --> 04:25.220
and pads that don't
adhere to the hook disk.

04:25.220 --> 04:28.190
This is a good time to ensure
which size of pads you have.

04:28.190 --> 04:30.743
Either the 3/4 inch, or the one inch.

04:32.070 --> 04:34.290
If any of these problems
exist with the pads,

04:34.290 --> 04:36.210
replace the appropriate pads.

04:36.210 --> 04:38.040
Regardless of the inspection results,

04:38.040 --> 04:41.920
pads should replace after
six months of continuous use.

04:41.920 --> 04:44.440
Before we install the
suspension system pads,

04:44.440 --> 04:46.560
we must install the Night
Vision Device bracket,

04:46.560 --> 04:48.830
and the reversible helmet cover.

04:48.830 --> 04:51.130
The NVD bracket for this ECH is different

04:51.130 --> 04:54.030
than the bracket that was
originally fielded with the ECH.

04:55.850 --> 04:59.610
Here we have the bracket
screw and the bracket post.

04:59.610 --> 05:01.860
Start off by inserting the bracket post

05:01.860 --> 05:04.393
into the hole from the
inside of the helmet.

05:06.320 --> 05:09.223
Place the NVD bracket over the hole,

05:12.900 --> 05:14.933
and insert the screw from the outside.

05:19.120 --> 05:21.630
Hold it in place and then
grab a flathead screwdriver

05:21.630 --> 05:22.883
to secure it in place.

05:23.870 --> 05:26.863
Turn hand-tight plus a quarter-inch turn.

05:28.100 --> 05:30.700
If it comes loose during
use, simply tighten it up.

05:30.700 --> 05:32.730
However, after doing
this five or six times,

05:32.730 --> 05:34.440
replace the hardware.

05:34.440 --> 05:37.730
Let's take a minute to discuss
the placement of the screw.

05:37.730 --> 05:39.250
To ensure the proper attachment

05:39.250 --> 05:41.730
of your Night Vision
Device onto the bracket,

05:41.730 --> 05:44.950
the screw must be placed at
the very bottom of the slot.

05:44.950 --> 05:47.070
Doing otherwise will prevent your NVD

05:47.070 --> 05:48.440
from attaching to the bracket,

05:48.440 --> 05:51.470
because the head of the
screw will be in the way.

05:51.470 --> 05:53.750
For demonstration purposes,
we are going to loosen

05:53.750 --> 05:56.793
the screw so you can see
exactly where it should be.

06:04.170 --> 06:06.980
Prior to tightening the
screw, slide the bracket

06:06.980 --> 06:08.760
up towards the top of the helmet,

06:08.760 --> 06:10.560
and then tighten the screw in place.

06:19.890 --> 06:22.010
You are now ready to
install the newly-designed

06:22.010 --> 06:23.760
reversible helmet cover.

06:23.760 --> 06:25.380
The new design allows you to change

06:25.380 --> 06:27.020
from the desert to the woodland pattern

06:27.020 --> 06:30.410
without having to remove the NVD bracket.

06:30.410 --> 06:34.003
Start by passing the precut
hole over the NVD bracket.

06:47.070 --> 06:48.860
Continue to install the helmet cover

06:48.860 --> 06:51.710
until all the hook and loop
straps are securely in place.

07:03.040 --> 07:06.650
We are now ready to install
the suspension system pads.

07:06.650 --> 07:08.720
The pads are designed to absorb energy,

07:08.720 --> 07:12.410
in order to reduce head injury
risk from blunt impacts.

07:12.410 --> 07:15.210
The crown pad sits directly
in the center of the helmet.

07:19.900 --> 07:21.960
The front/rear pads
are placed at the front

07:21.960 --> 07:23.110
and at the back of the helmet,

07:23.110 --> 07:25.060
flush with the inside of the edge trim.

07:38.840 --> 07:40.160
The hardware inside the helmet

07:40.160 --> 07:42.160
where the retention system
attaches to the helmet

07:42.160 --> 07:45.560
in the four places must be
covered by the four oval pads.

07:45.560 --> 07:47.660
As with the front/rear
pads, the four oval pads

07:47.660 --> 07:50.010
must be flush with the
inside of the edge trim.

08:08.040 --> 08:10.330
The oval pads may be
placed in either a vertical

08:10.330 --> 08:14.060
or a horizontal configuration,
or at any angle in between.

08:14.060 --> 08:16.410
The vertical configuration
maximizes airflow

08:16.410 --> 08:18.430
for better temperature regulation.

08:18.430 --> 08:20.390
The horizontal configuration makes a seal

08:20.390 --> 08:22.210
around the user's head,
and is better suited

08:22.210 --> 08:23.310
for cold environments.

08:34.670 --> 08:36.930
However, regardless of
the angle, you must ensure

08:36.930 --> 08:39.610
that all hardware is
covered, and that the pads

08:39.610 --> 08:41.760
are flush with the
inside of the edge trim.

08:45.839 --> 08:47.710
It must be emphasized
and clearly understood

08:47.710 --> 08:49.810
that using fewer than the seven issue pads

08:49.810 --> 08:51.560
is not authorized.

08:51.560 --> 08:53.560
Removing the suspension system pads

08:53.560 --> 08:56.750
is equivalent to removing
the airbags from your car.

08:56.750 --> 08:58.700
We will now demonstrate
the proper procedure

08:58.700 --> 09:01.030
for donning the helmet
and making adjustments

09:01.030 --> 09:02.263
to the retention system.

09:03.130 --> 09:05.910
Your ECH should be adjusted
for a snug, secure fit

09:05.910 --> 09:08.140
at all times when the helmet is worn.

09:08.140 --> 09:10.870
Failure to do so may result in injury.

09:10.870 --> 09:12.500
When donning the helmet for the first time

09:12.500 --> 09:14.760
in a cold environment, it may be necessary

09:14.760 --> 09:16.200
to wear the helmet for a few minutes,

09:16.200 --> 09:18.780
or otherwise warm the
pads, so that the pads

09:18.780 --> 09:21.140
will conform to the shape of your head.

09:21.140 --> 09:23.170
In addition to wearing the
helmet to warm the pads,

09:23.170 --> 09:25.620
you can also place them in your pockets.

09:25.620 --> 09:27.580
As the pads warm up and
conform to the shape

09:27.580 --> 09:29.840
of your head, it may be
necessary to re-tighten

09:29.840 --> 09:31.053
the retention straps.

09:31.990 --> 09:33.830
Prior to donning the helmet, and ensuring

09:33.830 --> 09:35.800
all seven pads have been installed,

09:35.800 --> 09:37.870
loosen the retention straps all the way

09:37.870 --> 09:40.520
by sliding the four slides
towards the helmet itself.

09:41.570 --> 09:43.090
Also loosen the nape pad strap

09:43.090 --> 09:45.890
by sliding the slide to the left.

09:45.890 --> 09:48.100
As you don the ECH, press down to ensure

09:48.100 --> 09:50.650
the center crown pad touches
the top of your head,

09:50.650 --> 09:52.290
and then buckle the chinstrap,

09:52.290 --> 09:55.460
ensuring that your chin is
centered in the opening.

09:55.460 --> 09:57.720
At this point, adjust all four side straps

09:57.720 --> 09:59.720
and the nape strap by sliding the slides

09:59.720 --> 10:01.610
in the appropriate direction.

10:01.610 --> 10:04.120
Adjust the left and right
sides simultaneously,

10:04.120 --> 10:07.730
until the fit is snug,
secure, and comfortable.

10:07.730 --> 10:09.530
Check the helmet's stability by attempting

10:09.530 --> 10:12.270
to rock the helmet back
and forth on your head.

10:12.270 --> 10:14.770
If the helmet rocks, it is not stable.

10:14.770 --> 10:17.050
If necessary, adjust
the nape strap further,

10:17.050 --> 10:20.450
until the helmet is stable,
and then recheck the stability.

10:20.450 --> 10:22.610
A properly-fitted helmet
will allow the wearer

10:22.610 --> 10:24.730
to see just the brim of the helmet,

10:24.730 --> 10:26.660
which equates to the
brim being a half inch

10:26.660 --> 10:28.450
above the eyebrows.

10:28.450 --> 10:31.150
We can check that using the
two-finger forehead check.

10:32.330 --> 10:33.790
The lower edge of the helmet will sit

10:33.790 --> 10:35.710
at the top of the ear
canal, and there will be

10:35.710 --> 10:37.460
no loose straps.

10:37.460 --> 10:39.900
If after all adjustments
are made, and the crown pad

10:39.900 --> 10:42.670
does not touch the wearer's
head, more than half an inch

10:42.670 --> 10:44.750
of the forehead is exposed,

10:44.750 --> 10:46.610
the wearer does not see the brim,

10:46.610 --> 10:48.420
or if the helmet is simply too tight,

10:48.420 --> 10:49.990
obtain a larger helmet.

10:49.990 --> 10:52.920
Likewise, if the helmet
seems to be the right size,

10:52.920 --> 10:56.460
yet it is still too loose
and/or sits too low on the brow,

10:56.460 --> 10:58.310
try using the one-inch pads.

10:58.310 --> 11:00.803
If it is still too big,
obtain a smaller helmet.

11:06.310 --> 11:09.323
Wipe the exterior of the
helmet shell with a damp cloth.

11:10.320 --> 11:12.750
Clean the hook disks
with a soft bristle brush

11:12.750 --> 11:14.700
to remove dirt and debris.

11:14.700 --> 11:17.820
Hand wash the pads with
mild soap and water.

11:17.820 --> 11:19.810
Rinse them well and allow to air dry.

11:19.810 --> 11:22.150
Never machine wash or dry.

11:22.150 --> 11:24.670
Clean the retention
system with a damp cloth.

11:24.670 --> 11:27.340
For the leather components,
clean with mild soap,

11:27.340 --> 11:30.330
rinse thoroughly, and wipe
dry with a clean cloth.

11:30.330 --> 11:32.340
Though the ECH is extremely durable,

11:32.340 --> 11:35.130
do not expose to an external heat source.

11:35.130 --> 11:37.410
Do not paint the helmet
shell due to degradation

11:37.410 --> 11:39.300
of the infrared signature, and reduction

11:39.300 --> 11:40.940
of flame resistance protection.

11:40.940 --> 11:43.130
Do not use it as a hammer, a shovel,

11:43.130 --> 11:45.973
a chair, or any other unintended purposes.

11:47.060 --> 11:48.930
We are now ready to
demonstrate the procedure

11:48.930 --> 11:51.480
for determining the correct helmet size.

11:51.480 --> 11:53.120
Please refer to the quick reference guide

11:53.120 --> 11:55.190
for further details, if necessary.

11:55.190 --> 11:56.840
The first step is to measure and record

11:56.840 --> 11:58.310
the wearer's head length.

11:58.310 --> 12:00.670
Using a caliper, measure the distance

12:00.670 --> 12:03.340
from between the eyebrows
to the back of the head.

12:03.340 --> 12:05.650
Now place the tip of the
caliper on the starting point

12:05.650 --> 12:07.460
of the sizing banner, and take note

12:07.460 --> 12:09.820
of the actual helmet size indicated.

12:09.820 --> 12:12.340
The next step is to measure
the wearer's head width.

12:12.340 --> 12:13.980
Again using the caliper, measure

12:13.980 --> 12:16.080
the maximum horizontal width of the head

12:16.080 --> 12:18.400
just above the ears and again,

12:18.400 --> 12:20.160
using the sizing banner, take note

12:20.160 --> 12:22.070
of the helmet size indicated.

12:22.070 --> 12:23.980
Now, using a tape measure, measure

12:23.980 --> 12:25.720
the maximum circumference of the head

12:25.720 --> 12:28.210
just above the ears,
and lay the tape measure

12:28.210 --> 12:31.220
on the sizing banner and take
note of the size indicated.

12:31.220 --> 12:33.530
The final step is to compare
all three measurements,

12:33.530 --> 12:35.330
and select the measurement
that corresponds

12:35.330 --> 12:37.430
to the largest of the three.

12:37.430 --> 12:39.430
That is your ECH size.

12:39.430 --> 12:42.240
For example, if the head
length corresponds to a large,

12:42.240 --> 12:44.870
and the other two measurements
correspond to a medium,

12:44.870 --> 12:46.883
you will still select a large helmet.

12:47.910 --> 12:50.740
If for some reason you do
not have the sizing banner,

12:50.740 --> 12:52.610
simply use the caliper and a ruler

12:52.610 --> 12:54.540
to determine the measurements.

12:54.540 --> 12:56.800
Use this sizing chart
in order to determine

12:56.800 --> 12:58.000
your helmet size.

12:58.000 --> 12:59.830
The sizing chart is also available

12:59.830 --> 13:01.460
in the quick reference guide.

13:01.460 --> 13:04.470
Let's take a quick minute to
discuss the sizing kit itself.

13:04.470 --> 13:06.470
When your unit receives it,
it's going to be packaged

13:06.470 --> 13:09.010
something similar to this.

13:09.010 --> 13:10.870
The caliper may or may not look like this,

13:10.870 --> 13:12.560
but either way it's going
to be a working caliper

13:12.560 --> 13:15.110
that will allow you to get
an accurate measurement.

13:16.410 --> 13:19.050
The sizing chart is what
I want to discuss now.

13:19.050 --> 13:21.340
As you can see, from being
shipped and folded like this,

13:21.340 --> 13:23.740
it's gonna have some
natural ripples in it.

13:23.740 --> 13:25.820
You need to give the chart
a chance to lay flat.

13:25.820 --> 13:28.167
You can assist that by using the grommets

13:28.167 --> 13:31.430
and anchoring it with 550
cord or even nailing it

13:31.430 --> 13:34.100
straight to a table through the grommets.

13:34.100 --> 13:35.900
You can duct tape it, do
whatever you gotta do,

13:35.900 --> 13:37.500
but you gotta, before
you measure a Marine,

13:37.500 --> 13:39.330
you want to make sure
that it's nice and flat.

13:39.330 --> 13:40.910
As you can see, the one on the table here,

13:40.910 --> 13:43.710
this was given a couple of
hours, it lays flat naturally.

13:43.710 --> 13:45.790
If you can't find a
flat table, you can use

13:45.790 --> 13:47.980
a firm piece of cardboard,
and you can see here

13:47.980 --> 13:49.730
it lays nice and flat.

13:49.730 --> 13:52.400
If it's windy outside and
this doesn't work for you,

13:52.400 --> 13:54.760
consider taking a piece of plywood,

13:54.760 --> 13:58.470
anchor it in the four corners,
and it'll lay flat on there.

13:58.470 --> 14:00.020
Finally, I'll demonstrate how you can do

14:00.020 --> 14:02.140
mass fielding with your unit outside.

14:02.140 --> 14:03.600
The more charts you have the better,

14:03.600 --> 14:06.040
but we'll demonstrate it
with one chart, one Marine.

14:06.040 --> 14:08.220
Simply, you would line up
all the Marines in a column,

14:08.220 --> 14:10.620
and you can conduct the
sizing one after the other.

14:10.620 --> 14:12.910
If you take the first
Marine, and you have him

14:12.910 --> 14:16.333
cradle the chart, I
would step to his side,

14:16.333 --> 14:18.390
and I conduct the first measurement,

14:18.390 --> 14:20.030
which is the head length.

14:20.030 --> 14:21.940
Again, ensuring that I touch the skin

14:21.940 --> 14:24.300
but I do not indent the skin.

14:24.300 --> 14:26.450
I lay the caliper on the chart,

14:26.450 --> 14:29.653
and we see we have a
measurement of medium.

14:30.490 --> 14:31.893
Now I'll do the head width.

14:34.070 --> 14:35.363
Just above the ears.

14:42.800 --> 14:46.083
And here we can see we
have still a medium.

14:47.240 --> 14:49.363
Finally we'll do the head circumference.

14:58.270 --> 15:01.210
We measured him at 22 and 1/2.

15:01.210 --> 15:02.090
Watch what I do here.

15:02.090 --> 15:04.120
I'm gonna lay the measuring tape

15:04.120 --> 15:06.330
right on the chart, and
I'm gonna press it down

15:06.330 --> 15:08.430
to make sure that it's nice and flat.

15:08.430 --> 15:11.640
I'll follow it all the way to 22 and 1/2,

15:11.640 --> 15:13.870
and I'm right on the edge of medium,

15:13.870 --> 15:16.060
so this Marine is a medium ECH.

15:16.060 --> 15:18.270
I tell him what size he
is, he can go get it,

15:18.270 --> 15:21.270
I'll take the chart, and then
we'll do the next Marine.

15:21.270 --> 15:22.710
I have a save drama for you.

15:22.710 --> 15:24.700
Let's talk about the
measuring tape itself.

15:24.700 --> 15:26.560
Depending how they crimp
the tip, they may have

15:26.560 --> 15:29.090
cut you short starting
at the one-inch mark.

15:29.090 --> 15:30.130
It's easy to check that.

15:30.130 --> 15:32.210
You can just take it and
lay it up against a ruler.

15:32.210 --> 15:34.190
You could take it and
lay it up against itself.

15:34.190 --> 15:36.170
Or I'm just gonna show
you how I can measure it

15:36.170 --> 15:37.730
against another measuring tape.

15:37.730 --> 15:39.680
I'm gonna take the tip, I'm gonna lay it

15:39.680 --> 15:43.470
right on the one-inch
marker, and my one inch

15:43.470 --> 15:45.350
of this tape should
line up to the two inch

15:45.350 --> 15:46.790
of this tape.

15:46.790 --> 15:48.630
And as you can see, it clearly does.

15:48.630 --> 15:50.870
So we know that this one
had been crimped correctly.

15:50.870 --> 15:53.420
Make sure that you always
check them before you use 'em.

15:53.420 --> 15:55.560
It is imperative that
you follow the procedures

15:55.560 --> 15:58.210
outlined in this video and
the quick reference guide.

15:59.120 --> 16:01.350
Marine Corps Systems
Command produced this video

16:01.350 --> 16:05.560
in order to demonstrate the
proper use and care of the ECH.

16:05.560 --> 16:07.050
There are several other training videos

16:07.050 --> 16:09.270
on SYSCOM's YouTube
channel that demonstrate

16:09.270 --> 16:12.160
the proper form, fit, and function

16:12.160 --> 16:14.040
of select infantry combat equipment

16:14.040 --> 16:17.130
such as the Plate Carrier,
and the USMC Pack.

16:17.130 --> 16:18.840
Go check them out.

16:18.840 --> 16:20.760
For more information regarding the ECH

16:20.760 --> 16:23.300
