What the fuck does this mean?

DM73 is just a slightly higher pressure DM53, but it probably wouldn't matter in most situations, just like in game, sure. Also I'm pretty sure the Germans already put some anti ERA features in that one.
M829A3 added a breakaway steel tip and fattened up the dart to better deal with new, anti kinetic ERA. Other new munitions would be stuff like Shard Mk.1/2, KE2020neo, KE-W A4 and AKE-T. I know the Japanese and Koreans have something too, but I forgot the name. The chinks probably have something too.
