While RTOs are pretty cool, they're somewhat redundant, at least in my opinion. SL already gets command comm access and can give orders. So what if we made RTO perform a separate role? If groundside comms didn't exist, the RTOs' phones would be vital to marine communication and they could actually be useful beyond being knock-off SL. Also they should probably have engie and construction at level 1, not 2.
SL could get a tablet/whatever to make squad announcements.
This would make the squad sticking together more important.
Scout would probably need a phone of his own though, since one of the kit's functions is JTAC.
I do vaguely remember something like this getting mentioned when techwebs were first announced, but still, seems like a good option.
