Apply a little anti-seize
compound, NSN 8030-01-087-
8254, to the threads before
installing the plugs. That lets
you tighten the plugs enough
to keep them from vibrating
loose, but makes them easier
to open when you need to.
Just make sure you put
the compound on each plug’s
threads
and
the threaded
portion of the hull. That way,
all the threads are coated
and the plugs won’t stick.
C
rewmen, you wouldn’t believe how much water can collect in the hull of your Stryker.
It drips off wet boots and uniforms, trickles in through open hatches, is left behind after
leaving the wash rack, and seeps in through loose hull drain plugs during fording.
Dear Half-Mast,
If the Bradley’s aerial sight can’t be mounted or is broken, the Bradley
is considered NMC. But the new armored commander’s shield (ACS) makes
it difficult to mount the sight and with the sight mounted you can’t fully
elevate the M242 gun. Is there any solution for this?
SGT H.H.
Dear Sergeant H.H.,
Yes. Turn in the aerial sight. The Army considers the protection provided by the
ACS more important than the aerial sight. This removes the NMC criterion for
the sight. Paragraph 8d of MWO 9-2350-294-55-23 authorizes you to remove the
aerial sight and send it to:
Red River Army Depot Munitions CTR
Hwy 82 West CL V TPF
Gate 44 Bldg 184
Texarkana, TX 75507-5000
DoDAAC W45G19

The Problem
There are at least three ways that water can damage your Stryker:
1.
Water that collects under the floor
plates will rust the ramp chains;
connectors on the air, hydraulic and
fuel lines; the ABS system; and
pretty much anything else that’s
made of metal.
2.
If you’re in a cold-weather
environment like Alaska, the water
freezes. Water expands as it freezes,
rupturing lines and ±ttings and causing
even more damage.
3.
As temperatures go up, the water evaporates and condenses on radios and other
electronic gear. Enough moisture can short out electronic equipment.
The Solution
The only way to get that water out is to open the hull drain plugs on the bottom of
your Stryker. There are 15 plugs, so make sure you open
all
of them or you’ll leave water
behind.
Make sure any water drained from the hull goes into a drip pan and is disposed of
according to your unit’s SOP.
Of course, you don’t want water to get back in through the plugs, so make sure you
reinstall ‘em before operation. And do it right. Plugs that are too loose will vibrate free.
Plugs that are too tight are hard to open and are more likely to be left closed when
draining is needed.
