Straying into new territory here, so sorry if this is a stupid question.
I recently bought a little tankette from an ebay seller:

Its obviously based on a Renault Chenillette UE, but is lacking any armament.
Now, I've had one of my periodic silly ideas, and was wondering where would be the best place to mount a Vickers MG on it. I don't really fancy a static mount, or too much faffing with plasticard to make a raised turret or gun shield for it, so could I get away with a pintle on the back, say in the cargo area? It would mean that the commander would have to pop out of the hatch to fire it, but I kind of like the bodged together recklessness of the idea.
In my funny little mental world the tank is only going to be used as a kind of ram-raider, but I'd like it to have the option to be used as a mobile strongpoint and bring some extra firepower to bear.
So any other ideas, or should I just go ahead and do whatever I think is right?
