hose new fat screen HDTVs are great, aren’t they? Those nice bright screens,
crystal-clear pictures and easy-to-use controls For brightness and color have kinda
spoiled us all.
That may be why some operators run
into problems with the integrated sight
unit (ISU) on their Bradleys. They ±gure
they can get an even better picture iF they
can just adjust the reticle brightness knob
a little bit more.
OFten, that “little bit more” is a little
too much. The knob snaps and you won’t
be adjusting anything until it’s replaced.
So, adjust only iF you must. Just don’t
try to Force the issue, or the picture you’ll

hen you’re launching or retrieving your AVLB’s bridge, you’ve got a whole
lotta weight swinging through the air at one time. So it’s important to make sure
everything’s tight and secure beFore you begin.
Take the bridge’s end panel tie rods, For example. IF the securing nut loosens, the
tie rod can move. Combine that slight back and Forth movement with the stress oF
Folding or unFolding the bridge and the tie rod can bend. Even worse, iF the nut comes
completely oFF, the tie rod can slide out and the bridge starts coming apart.
So check each oF the nuts beFore operation. TM 5-5420-203-13 is being changed
to add a torque requirement oF 25 lb-Ft For the two tie rod nuts. IF the nut shows signs
oF damage, replace it with NSN 5310-01-032-2318. IF any other tie rod part needs
replacement, check out ²ig 5 oF TM 5-5420-203-24P For the NSN you need.
