8:25 I will never understand why "people who wear armor in a Sci-Fi setting" DON'T have the gun as part of the forearm armor. You could have it as an outside or inside wrist-mount ... and the power supply for the laser blaser can be "anywhere" on the armor OR with a "quick supply power pack" that is easily replaced. Hollywood designers are "meh" ... including "bombers" in a light-speed battle and horsies to ride across a spaceship ... and so on.
