Um.. it could be more normal sized, but it is gonna be difficult doing that. I would have to either; rerender all the original frames (esentialy remaking the entire unit), or resample the individual frames, which I think will make it jumpy as hell. I will give it a go, though perhaps some on else would like to do it.
Besides, I thought for a unit as rare and expensive as the Tiger II you would want something realy menacing.
Remember that during the war, nearly 30,000 german tanks were produced, and only 489 of them were tiger IIs.
For myself, I am going to make half srength regiments with half HPs but great stats that can be spread among the bulk of the main panzer force, providing heavy support, but in limited numbers. In this role a regular sized tiger just wouldn't cut it.
