Sketched this out in an OC session with some peeps.
General ideas practice for mechs, gotta keep the brain loose. (pfft, I'm just having fun)
A mid weight multi-role mech built of decent tech equipment and weapons.
A light auto cannon in a torso turret provides anti personnel / light armor defense.
A rail gun in one arm is it's primary weapon, able to engage a wide variety of targets, land and air.
Then a missile launcher in the other arm can attack indirectly and fire several specialty munitions.
