Bazookas don't counter well the flak-truk, unless you have good covers. What you need to do is using your zooks as a defensive scarecrow until he does a wrong path.
In 1vs1, lately vs OKW I play really aggressively 4/5 rifles to cpt + Atgun + stuart and focus his building. Objective is to kill his T1/T2 before he get too strong. That a bit of a all-in when I'm ready, I let him cap all the map if he wants to but I move everything, ambulance included to get his building down.
Its fun to play
