You definitely came to the right place! By the way, the mods were likely only trying to point you to the fan design forums. In general, design discussions belong here or in "Non-Canon Units".
Here are stats for the jeeps I mentioned (they use fractional accounting):

I use both with my non-canon ComStar unit in 3053.
Fireangel will likely have better ideas for the infantry than me, but I'm partial to high damage rifles with long range laser rifles as secondary weapons to extend the range to 3/6/9. If you can talk your GM into early production Federated-Barrett 42Bs, you could get to 6 points of damage per squad:
5 Federated-Barrett M42B at 1.02 each = 5.1
2 Intek Laser Rifles at 0.21 each = 0.42
Total = 5.52, rounds to 6
I generally prefer the Intek because it only uses 2 power points per shot. That means it can use high capacity micro-power packs that only weigh 20 grams each for 10 shots, leaving room for disposable weapons or mission equipment.
Failing that, you'd want either standard auto-rifles or Imperator AX-22 Assaults. The Imperators are half a kilogram lighter, but technically FWL weapons. 7-man squads would come out to:
5 auto-rifles or Imperator AX-22 Assaults at 0.52 each = 2.6
2 Intek Laser Rifles at 0.21 each = 0.42
Total = 3.02, rounds to 3
If you want to really push the limits and ease conversion to Battle Armor organization some day, roll with 4 trooper squads armed with some Mauser 1200 LSSs somehow acquired from the WoB:
2 Mauser 1200 LSSs at 1.04 each = 2.08
2 Intek Laser Rifles at 0.21 each = 0.42
Total = 2.50, rounds to 3
The auto-rifle version can only get to two points of damage by using one of the other range 3 laser rifles (Mark XX or Starfire).
