my last match(lol) was in FEB, in Kamu afghanistan, not quite same thing but heres what I learned
1. trust your zero
2. know your range(practice estimation)
3. closer is not always easier
4. less than 15 degrees of angle doesnt change the shot much, but 30 degrees does, lol
5. practice stable positions learn where is solid
6. cross talk between squad members
........ You ain't Sh^T!!!!!!!
