I really never see anybody do this, but.
Put your shock troops into scout cars or a m5.
Drive em into the enemy weapons team and they have to retreat or suffer.
Playing Ostheer and get harassed by a t70. Faust it and put your shrecked panzer grenadiers in a open half track and take it out.
Usf and Ukf can do this too.
Halftrack mgs even has high dps, by

Try it out and take the enemy by surprise!
