Just copped. what do I need to know for success brehs
Support and Engineer are the best classes. Support more for making your health regen with the supply bag. Engineer for taking out vehicles. Assault is only good for respawn beacon to flank with a suppressed weapon. You'll be too low level to do that right now.
If you pick support and want to defib someone charge it up until you hear a beep. This will revive someone with 100% hp instead of 50%. That's if you have time. Also check if a person can be revived because dudes will ask for a res infront of 3 enemies. You can use your smokes for cover, escape, or pushing.
Try to unlock the M4A1 and level it up until you can use the DRS IAR. You can stay with the M4A1, use the DRS, or use; QZB, NVO assault rifle, KTS LMG, Kord, PW5A3, SGX, SCW-10, or TR-7. IMO the drs is good to use at all ranges and easy to use.
For the DRS IAR the attachments you want are(these are normally the best for all weapons ive seen so far):
Whatever sight works for you
Heavy extended Barrel
Lightened suppressor. Use regular when you unlock it. Before that use linear converter or compenstater.
Underbarrel use folding stock at first then one of the angled ones.
Use 30 fast mag for the clip
Red then green laser on top
You can use a light on the side but I don't like them. They help with hip fire recovery so your bullet spread goes back down faster.
