also there 4 different class... Assault, Engineer, Support, & Recon... Each one is way different then the other.
Assault: you can bring people back from the dead (that good cause it save a ticket) or if they running low on life drop a med pack...
Engineer: You can fix the vehicles that are about to blow up...
Support: alot people forget about being this til they low on ammo I cant tell you how many point I get pre match just on ammo pack alone...
recon: You get a spawn becon and choose not only where you wanna spawn but you squad can spawn there too and tugs let you know where people are close by and if they get killed that points...
All this is gets you points... you do nothing but throw some boxes down or fix a tank and you get points...
This game is about about 10% k/d and 90% team based...
