I know it is just an anatomic study but I would more image that an Focco would use an staff or bare hands in an low tech fight. Stabbing an slashing to wound and kill seems to be out of character.

Did the Procyonians ever developed advanced weapons? I wounder how he would like as an (aliens) space marine.

As long as there are knives, there is a possibility to fight with one. However, I have some staff poses archived somewhere too... stay tuned.

As for advanced weapons, they did, naturally, but the patterns and motivation of advancement were not quite like ours. Not sure if a marine role is appropriate, though.
