It's only a problem in those corridors before the map opens up. Personally I'd remove that class and spawn them on the map at the point where the tanks are available. It possible because that map spawns StGs and an MG-42 in the armoury after the door is blown off, and spawns AR ammo near the mounted machine guns.

I also realised the ammo boxes and med kits respawn on your knife slot eventually after you've used them. Not sure if it's just on that map though.
