Radios are super-cool, and when the radio code was announced there was a suggestion that mid-band radios for corporate security forces, high-end solo teams, and the like would be coming. I don't think we've seen that yet, but I hope we will.
Particularly, what I'd like to see are 'security radio headsets' that act like mid-band radios and can be worn under a helmet. I'm thinking the classic 'secret service earpiece' kind of look, though I suppose 'special operations radio boom' isn't bad either.
I think it's a little silly that if corpsec wants a radio helmet, it has to be atomic orange or neon green, and also that you can't wear a radio with a helmet. Make them expensive to justify the advantages, probably.
