Not sure where to start, so I'll start with some pre-worked ballistics.

[hider=Main cartridges]
Pistol Caliber:
Gen I - 8mm Nambu
Gen II - 7.62x25 TT
Gen III - 6.5x25 CBJ; 9x19mm Parabellum; .40 S&W; .357 SIG
Oddball: - 2" .410 (pretty much a .458 SOCOM, used for blowing hinges off doors with a silencer... or riot control)

Intermediate caliber:
6.5x55mm Sabot Light Armor-Piercing (long story short, this bullet can slice through about an inch and a half of RHAe)
7.62x39mm

Full-caliber:
8x50R Lebel
7.62x54R

Heavy-cal:
12.7x81R HMG round (Breda/Meji origin)
23x88R Light cannon
23x44mm HV-Grenade (implemented alongside rifle-grenades and rockets)
35x125mm Auto-Cannon

Light ordnance:

82mm recoilless-gun / Mortar (requires swapping baseplate and adding tripod) <-- Oversize warhead offers nuclear option at section-level[/hider]

[url=http://en.wikipedia.org/wiki/Section_(military_unit)#French_Army]General section-layout will be similar to but not exact to that of an Combat-Groupe[/url]
So one GPMG, one mortar, a sharpshooter, and three riflemen with a metric crud-ton of rockets and grenades. [i]Oh, and a tank with pretty much the same loadout as the entire squad.[/I]

Some of these men will be wearing power-assisted assault armor. Nothing fancy really, just something that allows a walking-tank to leap off their tank and bum-rush their way into a building. The energy-reserves only allow for about 30 minutes of autonomous high-intensity combat, though.
-Hence the tier 0-2.

ECM, ECCM, and C3 will likely be a tad behind the FFW/Felin concept

300 meter Team
1. Type 81 /w under-barrel shotgun (double-barrel .410, 50 shells) and 3 rifle-grenades + Rockets (3)
2. Type 81 /w under-mounted 23mm grenade-launcher (5 shot) and 20 grenades
3. Type 81 /w 3 Rifle Grenades + 2 Rockets and launcher (Type 69)

600 meter Team
1. PSL Marksman-Rifle + Type 54
2. PKM General Purpose MG + Type 54
2. [url=http://en.wikipedia.org/wiki/B-10_recoilless_rifle]82mm Recoilless-Gun B-10[/url] + Type 79

Support Team: [url=https://www.youtube.com/watch?v=989EIptJ2Mg]WZ-131A Light tank[/url] (crew = 4)
1. Commander, Gunner, Loader/Radio-Operator, Driver (the Type 62 is odd that it has a spot for the loader in the hull)
Tank Armament: 85mm gun /w over-barrel ATGM, two 7.62x54 MGs (1 in hull, 1 Co-ax), 12.7mm HMG/23mm Autocannon (Pintle-mounts cmdr/gunner)
Crew Armament: 1 RPK, 3 Type 79 SMGs, ~50 hand-grenades and ~40 MON-50 mines that may be fitted to hull and command-detonated

Note: a YW531 APC would have allowed too many people into the fight.

Also, each man will have a pair of hand-grenades or mines (additional hand-grenades and mines stored with tank).
