What to do when facing the Obj 705?

Falathi: From my perspective: don`t get close as it will rather work in favor of 705. If you can go mid range there`s good chance you`ll damage him hitting the lower frontal plate, while he will take more time to aim and even then has decent chance to miss a shot. 

Also, don`t shoot at turret - it`s pretty much pointless. Retreating is also an option preferable to fighting at close distance.
