@ #1: Hm. I see your point. But: Look here, an advanced system.

The control station is big as a full-size fridge. No way you can haul that on your back.

@ #2: Since I'm not U.S. I didn't know. You have to be rich to place it on squad level.
The reason I would want to place a Spike-MR on company level, is that I don't want to grow the platoon into a mini-company.
And I mean, how many tanks will you encounter out there that made it through smart stand-off subammo >> fighterbombers >> fast-mover CAS >> a/t-helicopters >> smart artillery rounds, to finally wind up in front of your platoon? And for anti-structure jobs a RPG-style weapon or PGMM seems more cost effective to me.

@ #3: Didn't say it's fun . That's why using a MGL at platoon level.

@ #4: Ok, understood - in your platoon 60mm mortars and ATGMs would be capable of doing that.
