Couple of comments:

@ ATGM at platoon level: in a jungle or urban setting you don't need the range of a Javelin. Pure waste of money to use a USD75k+ weapon in a scenario when a RPG can do the job. And again: If you give squad leaders a precision targeting capability you have a lot of anti-tank/-structure capability w/o loading up lower formations with weight and weapons they might seldom need.

@ capabilities of Spike-MR: Very impressive, but no substite for the mortars.

@ MG 7.62 in lower formations: What about that FN Mk.48 at squad level? Doesn't have the range of a long-barrel GPMG, but a lot more punch than a Minimi. Coupled with a weapon like HK417 or the SCAT-HLB you'd have volume and precision.

@ using 35/40mm automatic grenade launchers for foot soldiers: I think for the weight a 60mm mortars delivers more capability. A thing like MGL-140 on platoon level looks more intersting to me.

@ my idea of a 80mm mortar at company level: I still like it, but the fact that you can haul only 50% of ammo compared to 60mm is a very strong point. Nevertheless one should look into the option of a short-barrel 80mm with a, say, 3.5kg grenade.

@ using 30mm+ to suppress ATGM crews: First you have to see them. Hard to do from a APC/IFV. When driving around in vehicles a system like AMOS/NEMOS seems more useful for the suppression job. (Besides hopefully having some kind of helicopter escort around, when you're in that situation -- not small war anymore, I guess).

And a question: What about the individual weapons of MG, mortar and missile teams? Nothing, or pistols, or MP7?
