In VN, I called armor and APCs Zippos because they got lit..
(some said zippo's because they had flamethrowers built-in)
The RPG & B-40 & M72 showed the effectiveness of a thermal charge against Iron. It all started with the development of the WWII Panzerabwehrwaffe.
The current technologies incorporate that charge with GPS & Thermal targeting technology to deliver.
Package that technology in a mobile artillery piece or rocket that can deliver BOOM from 40-50 miles,, Awesome..
Until Force Field technology is developed,,
Yes, Armor is on the losing end of the battlefield.
OBTW,, so is anything or anybody that has a thermal image..
