Uh, yeah just like you said there, there's not a whole lot outside weapon racks if grenades are being saved because of mortars. Mines, flamethrowers, offmap, etc, are all doctrinal and unreliable, like I said. Which leaves the Major abilities. Which is exactly my point. That's not a great deal of options.
It might've been simpler just to say "not having easy access to mines or flamethrowers makes it a lot easier to rifles to be armed to the teeth from weapon racks." I wasn't suggesting that USF isn't capable of spending munis for munis sake at all.
I was also operating under the notion that fully equipping squads of riflemen should result in not having any munitions to dump.
Still false. Mines are usually available through one mean or another, and there are a broad range of abilities with and without doctrines that can be pretty effective. If you are floating munis, grenades can still do a number, even with a mortar already providing fire support. M20 mines are neither doctrinal nor unreliable. Major arty against forward HQs are neither of those things either. I could further dissect your argument, but those points alone should suffice.
One more thing I would add is that munis are hard to manage for sovs as well and the expenditures for those other than mines or light vehicles tend to be based on doctrines. That is why it is my personal opinion that most of the useless doctrines for sovs would be useful if they could be put to some good use. This could be especially easy in doctrines like tank hunter, they could just use a buff.
Just so you know, I'm not entirely convinced that double BARs shouldn't exist, that's just not the reason why they should.
