These are some suggestions for the Gr2:
realistic reticles: first 1x is to aim without watching, the second is with the sights of aimpoint, iron sight, whatever.
kick door, walls that can be broken, breach door.
Give order to the other soldiers, like ¨clear¨, flash, grenade, hold, cover.
Formation close, open, in line, stair
The posibility to drop and pickup objets and gun, with a limits.
Than one team alpha gives the order to team bravo to follows, cover, etc.
Realistic maps, and special attentions in this, the maps of Gr It and Ds sucks, they are unrealistic, and we can not use in the corretly form the sniper, soo bigger maps with realistic distance, terrain, structure and not nesesary detail.
Expand the kit, for example, one kit will be primary weapon(rifle and carabine with his respective grenade launcher), secundary(pistol), tird grenade, flashbang, bomb ,etc.
Othed suggestion is the tactical light.
The bipod of the sniper rifles active or not.
realistic night vision, visible.
the wounded screaming and craiyng because the pain, and when they are in the floor and incapacited they shoot you.
The possibility of get off and put on the glasses.
Radio with orders and reports for the comand, like ofp
Team play like swat 3
uses the helicopter for sniper cover in the air.
and more but i cant remember, soo
see you later
