As someone who doesn't play larger game modes - are there specific FRPs you have in mind? I rarely see them used in 2v2 as the penalty to reinforce time is pretty punishing. Halftracks and anything else that isn't a true retreat point are pretty squishy. In my mind the OKW Med truck is probably the most likely offender as it's both sturdy and usually better protected with Flak Gun. Obvious tradeoffs of course with risking your tech structures and the significant resource investment.
In regards to COH3... if I see another faction with truck teching I will personally go to Canada and burn down Relic studios (kidding obviously but barely )
You have seen the SP Alpha, there are brits. USF Design is really close to coh1. If the same Route is followed for Brits.. You get a Truck !
