A tiger is almost a must when playing against USF and there are a lot of tigerdocs to choose from.
-Assault support gets my vote because of the unique strafe which is very handy against infantry. Lightning war is another excellent commander with G43. You can also taje the elite troops but im personally not a fan of that unit. (Speaking from 2v2 experience)
-Mobile defence
Pumas are great against soviet T3/T4 and command tank is nice against US.
-Joint ops was here originally but with both nerfs to howie and pak43 its not worth it. So I put anothe rtiger doc here.
This time the one with Assgrens. it offers good unit variation and the stuge is very nice against infantry
The pathing of the Kubel is so messed up because it has no crush, not even light. So if you try to move it across say, minks pocket, it will have to go around every bush and piece of wood. This makes the unit very slow and vulnerable.
Then again, it is just a normal car. And cars don't generally do well driving through forests.
Support weapons should be more reliable.
-Make mg reload sequence longer but give the manual ability to reload magazines
-Gunners should recrew and shoot mgs much faster, right now they sit 1-2 sec doing nothing before they finally aim and shoot
