Err... Summon Visor...? It's beyond me how you'd get a visor to act as a radio, and besides which, COM links already allow UNSC troops to communicate rather efficiently. As for corner shot weapons, I doubt it'd be in regular military use; more likely with SWAT units or Special Forces operators, acting in tight urban environments.
