SpecOps adds a set of Recon Armor that has a built in stealth field it becomes active when the player is sneaking (the field is not as good as a Stealth Boy's but that's to balance it out). The mod also adds 3 new weapons:

SpecOps 10mm Pistol:
Damage: 15
Clip size: 10
Spreed: .5
Noise level: Silent
Description: While almost identical to other silenced 10mm found in the Wasteland the SpecOps is more accurate and deals significantly more damage, but has reduced range and clip size.

SpecOpsAR:
Damage: 18
Clip size: 15
Spreed: 1.5~2.0
Noise level: Normal
Description: The SpecOpsAR is a modified version of the Chinese Assault Rifle. The SpecOpsAR has a reduced clip size and rate of fire then its competitors but makes up for them with increased damage and accuracy. The AR fires 3 round bursts.

SpecOps Rifle:
Damage: 75
Clip size: 1
Spreed: 0
Noise level: Normal
Description: The SpecOps Rifle is a high powered single shot sniper rifle with accuracy second to none. This Rifle will bring down all but the strongest enemies with a single shot.

Note: The SpecOpsAR animation is off, way off. It only looks right when you don't hold down the trigger. If anyone knows how to correct this please let me know so I can fix it.
