OKW trucks are absolutely front line. Most maps your trucks will always be in enemy mortar range. Again it seems like people are being way to dismissive of the fact that a brace like ability that disabled the trucks benefits in return for say 50% reduced damage (not 75% like Brit Brace) would be nice.
Maybe for your playstyle. But I would say the majority of games I watch OKW trucks are simply built in the base or the next territory out from it. Hardly frontline.
I think you overstate how "aggressive" OKW has to be. Being aggressive is certainly highrisk high reward but it isn't the end all be all of strategies. It isn't a hard concept. Don't want your trucks destroyed? Don't build them outside of your base. Especially with the ML20 Nerf rngJesus be praised.
There is no reason to give brace to things that do not HAVE to be built near the front line.
And as others have said, when OKW trucks cost pop cap then making them easier to defend on the frontline should be considered. (3 pios, 3 medics, 2 gunners)
This less about making killing emplacements easier, more the double standard that other factions have to make significant sacrifices while recieving less.
This is such a useless and tired argument considering the game is based around asymmetrical balance. There is tons of crap that allies have that would make Axis better and vice versa, but that doesn't mean they should get it.
