Forum:Mount Command?

Has anyone else seem the 'Mount' command show up on Mass Effect?

I am in the Gemini Sigma - Ming and there is a derelict ship that has a load of booby traps set, When I get to the back of the room and stand in front of a box I can see the 'Mount' command which is weird as I have not seen it before...

Is it something they might have taken out or can other classes mount things...

Bit boring, I know, but there is nothing in the wiki about it...
