what about sniper training? u could have the sniper start off as just a normal infantryman then get selected (cos of his marksmanship skills) to do sniper training you could do a few missions based on training like ones where you have to hide and shoot a target without getting spotted then read a number that the trainer holds up. a walker has to be directed to your location so within 10 mins of the observer looking u fail, 20 mins u get low score, 30 mins high score. u could then pass out of training and be selected for delta doing sniper training there, shooting into buildings at targets and doing recce (recon) work, supporting attacks on bases, taking out officers and getting into hides (sniper positions) and then doing actual missions and CP sniper work (close protection(security)). this would be cool cos u could use BAS delta sniper for CP work, BAS ranger sniper for support missions with other teams and gillie suit sniper for when in sniper pair out on single ops behind enemy lines.
