Ok, other people had ideas for the Ostheer and USSR to use trucks instead of halftracks. I just wanted to add on to those ideas. The trucks are cheap but weak, and can possibly act as reinforcement points once armored up, but if armored, they lose the abillity to pull guns because of the heavy weight they carry already. The German would use an Opel Blitz, the Russians would use an American lend leased truck.
Firstly:
(Ost) Mobile Flak 88:
A version of the Flak 88 on a carriage that can be pulled by an Opel Blitz truck (which also serves to carry infantry). However, after being bumped and shaken, parts of the gun have became loose, making the gun less accurate and slower to reload as the Germans struggle to get the thing to work. It is also expensive and slow to move and set up if it is moved unhitched.
(Ost) Flakvierling AA/APGun:
Also mounted on a carriage like it's counterpart, the Flakvierling is a four-barrelled gun originally used for AA duties, although it makes a somewhat capable anti-personel weapon. It can be hitched to an Opel Biltz and towed around, but set-up time is slow and the crew cannot move it by themselves.
The Russian could just use the Zis for now, unless the team introduces a heavy AT piece for Russia.
