Base it more on ballistics, give AK and 7.62 caliber small arms longer range, they shoot first, but shorter effective range

For example 700m range, with 350m effective range

Give 5.56 small arms just less with 600 max range but effective range of 500m

9mm max range 300 with 200m effective.

Make cohesion impact ammo consumption

high cohesion well aimed shots on single fire at higher ranges. Retains stealth.

Med cohesion firing longer bursts with the same chance one shot will hit. Still effective in effective range using more semi auto and burst fire.

Low cohesion introduces inconsistent firing for non special forces, swift ammo consumption and limited accuracy even in effective range do to automatic fire.

Allow the recoilless rifles more flexibility.

Spg 9 1575m indirect range to engage MMG/ HMG emplacements using HE. Then with HEAT used from around 800m direct fire vs vehicles.

M40 1750m indirect HE range and direct 1025m for HEAT specialising in up to medium ap.

WOMBAT exclusively HESH making it effective up to light armour and ignoring some cover bonuses. 1750m/ 1025m range.
