The box next to the radios is for the Magnetic heading display thats in the driver station. Its a pain to calibrate. You need alot for room to do it cause you got to like drive in a circle like ten times. Plus the steps are in the TM 1o and the read like stero instructions

. The black boxes are for the TC and Drivers DVR's. They replaced the old fish bowls ANVVS's. You know the ones that would fall on you sack if you didnt latch in right.

.
They even Change the 50 cal charging handle. Its almost like a kick start lever on a old motorcycle. Its ok it beats the old M10s charging handles. They still break though. So the good old coke bottle or you sawed off 12in crosstip will do the job. oh you the pulgger mount in the turret AT KNEE HIEGHT

Does wonders on the knees and head when you climb in and out from the troop compartment.
Well see you around the forums..CHEERS and YAT-YAS!!!!!
