Yeah....welcome to the 80s. I've been wondering since I was a kid (i.e, the early 80s) why the US didn't have these, when everyone else in the fucking world did. I worked for a guy literally just prior to my exodus from the People's Republic of Kalifornistan who back in his much younger days, had humped a 75mm RR in Korea. According to him, it was the shit for killing bunkers, houses, light armored vehicles, etc. I happened, through a friend, to have an expended 75 RR round at the time and left it giftwrapped on his desk for Christmas on my final day (which was Christmas week).
His secretary thought I was demented, but I bet he got a kick out of it!
I mean, we made an "improved" RPG-7, and we've flirted with the Gustav for decades, been at war with a low tech enemy for a decade and a half and now FINALLY decide a cheap way to blow shit up at long range is smart? Holy fuck we could have been using these in Vietnam (instead of the LAW, which I've heard mixed reports on for blowing up bunkers). Never got to shoot any of these except the AT-4 trainer with the 9mm tracer, but seriously, how the hell did it take this long to adopt?
