to my understanding, u r wrong abt AA:SF.
its because lesser americans want to sign on. they change the name
from time to time, now called Special Forces because they include
"Special Operations" type missions for play.
getting the "Special Forces" status requires u to go to "SF school"
which requires the player to recognise popular war machines and
helicopters and a not so nice Escape and Evade training
mission.
however, not going to SF school, the player does not suffer from
any penalty (aiming, running), except he/she cannot play on the SF
maps as a SF... or play the SF exclusive maps.
same for the Medic school. if the player does not go the the Medic
school, and learn the very basics, he/she cannot be a medic in
game. however, the player does not suffer from any penalty (aiming,
running), except he/she cannot be a medic... which, gain points
very fast.
same for the Sniper school. if the player does not get Marksman in
his Rifle Range, or does not pass the 2 sniper training missions,
he/she does not suffer from any penalty (aiming, running), except
he/she cannot be a sniper... which sux because of the lag, unless u
wanna kill campers.
and 9mm Beretta vs AK47 in CQB... rushing snipers are just
screaming the words "pwn me!"
