Another idea is to use the Stuka AT strafe from the CAS commander:
- You are guaranteed to wipe forward assemblies in one pass
- You might be able to wipe an unupgraded & unbraced mortar pit in one strafe if you get lucky
Sadly, Bofors cannons seem unable to down the AT strafe. Thus you will not be able to get that kamekaze skillplane bonus on top of that
Obviously, the CAS commander may not be attractive (or even viable) for 1v1's anymore. However, with a teammate carrying you, you can use the commander to nullify Advanced Forward Assemblies (which is half of the part of what makes this commander so strong).
(LeFH is, of course, very reliable too, on maps where you can place it out of counter-barrage range)
