This pertains to a 2vs2 setting on building heavy maps. For the purposes of this discussion, it can be a Wehr/OKW mix or a double faction team set up.
In places like Ettlebruck, against top 100 players, I'm finding it impossible to deal with this tactic because even a mix of mortars, flamers, and HMG's can't stem the tide of rapid response conscript spam. It's pretty disheartening to see someone in the top 10 just blobbing them up too, kind of makes me feel this game is hopelessly broken.
The closer they get to the starting position, the more difficult it is to dislodge them, and the FHQ is up in no time at all, and a lot of the buildings in certain maps have ludicrously high HP. I'm not a beginner, so I'd really appreciate some tried and true methods in dealing with this SU strategy in high level situations.
There are not many maps specially in 2v2 FHQ is strong, one is probably the one you mentioned.
If you're a mix of Wehr/OKW, just don't panic, the Wehr player must get the Spearhead commander for the mortar ht for the incendiary barrage ability with totally kills the FHQ for 30 ammo. Don't get more than one ht cause you need fuel to prepare for their medium armor.
Usually with such strat, allies players spam cons/rifles, you can get a flak ht which would counter their spam in very hard but use it carefully in combo with mg and inf support.
btw, at the beginning of the game, specially when you see the FHQ commander in their list, always try to avoid the big building between the two vps, for as long as you can.
I actually find this commander very easy to counter even in this map cause it has no heavy tank, no elite infantry, and delays his teching a lot
