So I have to outnumber them or use vehicles. Perhaps it's my gamestile but i think Ostheer has a lot of troubles fighting units with submachine guns(commandos, shock troops). Assault grenadiers are doctrinal and not soo strong (quick start unit but weak for their role), pioneers are not made for combat and panzer grenadiers are for short-to-medium-ranged engagements (in short distances they lose against submachine guns).
Any infantry tactic against british commandos? Without light vehicles and mines I can`t fight them properly playing as Ostheer. They can beat MG42, Grenadiers even Panzer Grenadiers in 1 to 1 combat.
