[Take note: this is how to properly disarm someone. Always go to the outside of the arm, not the inside. ah yes I have been doing it wrong the whole time it seems cowering in fear was not the first step]
I still don't understand why the stupid guys from Disney made with red arm in "The Force Awakens"! Prob'ly the rebels found a way to import parts and ammo from a long ago and faraway source in the galaxy, Stark Industries.
