rewmen, water in the hull of your M113-series vehicle can dampen its ability to complete
missions.
Whether from rain or
washing your vehicle, water
rusts the fuel line and ramp
pump fittings under the
floor
plates.
Before
you
know it, leaks spring up and
your vehicle is down for the
count!
Luckily, damage like that
is really easy to avoid. There
are three hull drain plugs,
the bottom of your vehicle—
two at the front and one
at the back. Just open the
plugs and your water woes
will drain away. Make sure
that you replace the plugs
when the hull has drained.
Just be sure to follow your unit’s SOP on where to drain the hull—most likely at the wash
rack—since the water is sure to be contaminated with fuel, oil, hydraulic fluid or other
materials that are considered hazardous waste. You might be able to use drip pans if the
water level is low. Just make sure to dispose of the wastewater properly.
Dear Editor,
Getting the M240C machine gun correctly secured in the Bradley’s mount
can be tricky. You think the mount’s front pin is locked in place, but when you
fire you find it isn’t. That doesn’t help accuracy.
You must play with the pin to lock it in. When you think you’ve got it right,
have the driver move the M240C up and down. If the front pin’s still not
secure, the M240C will have the wrong elevation. This quick check will keep
your M240C on target.
