Is it possible to have an officer as part of the elephant crew? I tried adding it but the game just CTDs with no message. It seems unlikely so far, since for other units, officers up to 3 of them seems to have their own spot on the left side of the unit, with one more spot reserved for captain/general. But on elephants, the captain/general took over one of the crew's spots.

So has anyone did this or is it hardcoded?
