These tactics work well and leave the other 6 members of the team to assume whatever roles are needed to accomplish the objectives at hand.
This all depends on what level you are playing on. OR whether you are defense or offense.
But here goes. (Level 20 is best for these builds)
1 Soldier Medium w/AR underslung grenade launcher. Use whichever other attachments you like. Make sure your soldier has faster regenerating frags, wider blast radius, higher frag damage. A fact that most people don’t know about the underslung is that it uses your pips just like a thrown grenade but it explodes on impact. So the soldier can knockdown a horde of enemies in a choke point and mops them up with AR fire while they get back up. I play one man cleaning detail constantly to the frustration of my enemies while I get my team moved past enemy lines straight to the objective.
1 Engineer w/Gatling turret Body type not so important here but when I play this role I prefer light so I can get behind enemy lines quickly. The engineer is to harass enemy coming out of a spawn area. The best approach for me has been to place my turret diagonally from choke points so it’s harder to take out the turret from afar and then stand against the wall taking them out as they try to come around the corner to shoot your turret. A light with a SMG and drum mag can accomplish this easily.
Combining these two is devastating because the engineer can close in behind enemy forces and set up a turret to mop them up with the soldiers help while turning around to kill any reinforcements coming from a spawn that might shoot your turret from behind.
These tactics will easily help you clear frustrating choke points that bring you to a stalemate and restore the flow of battle.
I hope these tips help any of you that are struggling to find tactics that are effective for you at choke points. These are some of the ones me and teammates used earlier on.
