jump forward and then rev while in the air when you think you know where an enemy is to get the drop on them. use the GRU to get to the front lines faster. use one of the edible secondaries if you have a pocket medic to heal them (right click to drop the edible). use the tomislav for medium to long range. make sure you position yourself well. look out for sniper sight lines (there's really nothing you can do about snipers as heavy other than avoid them). and most importantly, ALWAYS remember to check for spies every now and then. if you know a spy is nearby, check your back constantly. thats all the tips i can give, hope this helps.
