I was on inXile's Veteran Advisory Panel, which was a thing they set up so they could ask a whole bunch of military veterans questions about things like weapons, radio stuff, movement, load outs, call signs, and other military-life information. It was a really neat experience.
Anyways, this was brought up specifically in our discussions. We spent a lot of time talking about what makes sense for weapon penalties, restrictions, and bonuses, and this was a thing that came up. Some of us suggested that assault rifles have both min and max ranges, outside and inside of which you would face penalties. Someone (actually, it may have been me but I can't remember!) also brought up the idea snipers should not be firing from the standing position, and should be penalized if they are firing without a "spotter" -- in this case, without a team mate standing X number of squares near the shooter.
I don't know how much of our discussions were used in the final product. I don't really like playing betas, so I can't check this out for myself. But seeing the sniper crouch -- even if it is just cosmetic -- is pretty cool, and proof that they were incorporating some of the things we were saying.
