I apologize. I didn't make myself clear. Let me clarify.
What I'm mainly wondering is there was any way that you could create more radios that could fit in your uniform. Instead of having a separate backpack as a radio. Using the RT-1523G prevents most users from carrying more gear. The group I run with has a complex structure where fireteams have their own channel for a group of 4, then have their squad channel with 4 fireteams and then finally a command net with air and ground mixed into it.
The problem we run into is a platoon leader in essence needs to talk on 3 different radios. With ACRE we can carry a 343, 152, and 148 without giving up our backpacks and still hear all three simultaneously.
