Combat realism? it's a damn crazy combat mod. It seems you've never used a weapon in real life.
You made a serious mistake without taking into consideration parameters such as:
1) the caliber of the bullets, respectively recoil after the shot. In your mod minigun bullets 5,56x45 caliber shooting at the same distance as a sniper rifle with a caliber 7,62x51.
2) Lethal force of a bullet 7,62x51 caliber about 3 times stronger than 5,56x45. Currently weapon damage is the same..
3) The weight of the weapon. In your mod no difference colonist took up a two-pound gun or 15-30 pound minigun. There is no decrease in the speed of movement. Usability of firearms plays a very important role, which affects everything.
7,62x51 vs. 5,56x45

For comparison:
5,56x45 Bullet weight - 3.6 g. Muzzle velocity of the bullet - 975 m/s. Muzzle energy ~ 1690 joules.
7,62x51 Bullet weight - 10.2 g. Muzzle velocity of the bullet - 840 m/s. Muzzle energy ~3600 Joules
P.S. Сurrently not playable at all.
