E-Bay has FM 17-12-2, Tank Gunnery, M60, M60A1, M60A1(AOS), and M48A5 Tanks (1977 edition) for sale for US $12.00 if anyone is interested in learning more about how the US Army found a solution without the use of electricity. Admit that the readouts were lighted so you could read them. I could hit a stationary tank size target reliably from a short halt at 4,400 meters if the 105mm M-68 cannon was zeroed properly. Freely admit that having both the target and shooting platforms moving on their X, Y, and Z axis complicates the gunnery problem significantly over what I accomplished.
I've ordered the FM. Questions. How the hell do you SEE a tank at 4,400 meters!? Do tank rounds come with variable powder charges? My guess is not, cuz you wouldn't want little baggies of powder sliding around the floor/deck/whaddayacallit.
Sounds like pretty good shooting!
