Maybe I'm not a pro, but watch out, I'm persistent.

BF4:
[ ✓ ] 100 ss with Main Battle Tank
[ ✓ ] 100 ss with Anti Air
[ ✓ ] 100 ss with Scout Heli (as a repair/co-pilot)
[ ✓ ] 100 ss with LAV

#4 in the world with the AA.
#3 in Mexico with the Tank
#10 in Mexico with the LAV
#2 in Mexico in repairs xD

*All of this until BF1 came out on October 21 2016 if I'm no longer in those places it's because I stopped playing BF4.

My stats aren't awesome because I'm a team player and I don't care much about that. You can tell by my 100+ SS with Scout Heli as a repair.
