create a Sturer Emil it was a tank destroyer with a gun that was stronger than the king tigers. However the drawback was that the Sturer Emil was lightly armored and the gun had quite a kick to it when you shot it. Oh, and the vehicle itself was unreliable, so at times the vehicle wouldnt turn on and would easily get stucked in between areas like a ditch. So maybe you could have the Sturer Emil have a damaged engine randomly and the crew would have to repair it. While the Sturer Emil could two shot a tank but would have a long loading time. Do note that the Sturer Emil was never in circulation it was an expiremental meant to counter the heavily armored KV series tanks. Do note that I am ratehr new to Eastern Front mod so if your not taking in any more ideas just simply say so.
