I never really did any infantry design, so here is my first attempt, feedback please.
The choice for the UAC/5 was because of its compromise between firepower and range, especially considering field guns don't jam.
I used just 3 squads as I wanted to limit the transport weight to a maximum of 50 tons.
I imagine that each squad has an open tractor with ammo bin that is connected to an Ultra AC/5 field gun, and having a ammo feed hanging between them.
