The B.F.X. Mod for 7.62 High Calibre

[R@S]

OK, here's the rub-down:
Kill 30 enemies and you advance to level 2, but if you have killed 70 enemies total you'll advance to level 3 and kill 280 and you'll advance to level 6. If you do missions for any faction it will automatically jump you toa preset level, this explains why you're on level 6 but only killed 197.

There is however some missions you have to do in order to progress up the CGL's, like 6 to 7 is such an occasion. There you have to do the convoy attack/defend if you want a higher CGL. Other barriers are 9-10 and 15-16, I think. Not sure, I have to check the code again, which is at home
