How do you use a stug then in an enviroment where your tankhunter can be lost to core infantry in a blink of an eye?
Either you can't read or you're intentionally missing the point. Twice now I've said that the Stug struggles against blobs because those blobs can't be countered properly. Either because the counter unit isn't up to the job (Ostwind) or previously effective counters (MG42) are swept aside by OP units (mortar, 2x M1919), which makes the blobs stronger than they would otherwise be.
