Yes, ammo independence is the advantage... since you're going with a fusion power pack, I figured that was important.
Unfortunately, there's a bug in MML.
Advanced Fire Control only applies to Medium (~= support) and Heavy weapons, not Small (=primary personal and a few light support weapons). Also, the heavy grenade launcher is unavailable in 3025. Redoing the weapons lists, I believe the 3025 pareto frontier is just:
Burst, Range 1: Machine Gun (Portable), 11.5kg (3kg reload), 1000 c-bills +10/reload (75/5 shots)
Burst, Range 2: Machine Gun (Support), 44kg (5kg reload), 1750 c-bills + 50/reload (100/5 shots)
Range 2: SRM Launcher (Light), 10kg (9kg reload), 1500 c-bills (2 shots)
Range 3: Support Laser (Semi-portable), 40kg (3kg reload), 3000 c-bills (21 shots)
Flame, range 0: Man Portable Flamer, 15 kg (8.4 kg reload), 100 c-bills + 2/reload (12 shots) Most units can't fire at things in the same hex.
Flame, range 2: SRM Launcher std 2 shot, 30kg (20 kg reload), 1500 c-bills + 450/reload (2 shots)
Overall, definitely still possible to do a full 5 points of damage, but ranges are reduced since we can't use small arms, there are no double damage weapons, and you can have at most one laser.
A couple side thoughts:
Should the Light SRM Launcher really have a 2 shot reload?
The threshold between "small" and "medium" weapons seems odd. Personal weapons are always "small", presumably even up to that 14kg Shrapnel sniper rifle but definitely including 12kg Mauser IIC. Support weapons seem to have a variable threshold with everything <7kg "small" while everything >8 kg is "medium". In that gap, you have the small 8kg light recoilless rifle and the medium light machine gun.
