Uncle Ted
In regards to Precision Guidance, The knowledge itself is quite old, both the Germans and USA were using precision guided weapons in the later years of WW2 and although these were radio-controlled, the technology advanced quite quickly with the US developing an infra-red homing missile for anti-ship use in 1945.
Laser guided weapons were developed in the 1960s with the US making use of them and other PGMs from 1972 (specifically during the Vietnam War).

I hope Paul is taking notes. He is the one who inspired this thread.

Appears to me to be either a thermal imager or a low light tv system.

That is the day/night sight. It was developed by Delco Electronics Division of General Motors. It has high and low power day channels and high and low power night channels.

I found most of the data from a Blog describing the XM800T's development...

The M-139 was a licensed copy of the French HS.820 20mm autocannon, used in aircraft and AAA. When Oerlikon bought Hispano-Suiza, they replaced their current 20mm design with it. The US used it only for a/c, where it was equipped with 2x 75-rd magazines. (This weapon, while excellent, saw little US use, as we developed the rotary M61 cannon and put that on aircraft.)

Anyway, see the attached...

Xm-734. One of the developmental evolutions of the m113 leading to the Bradley. I find it fascinating.
