Also, looks like in your picture they're wearing new plate carriers, with different magazine holsters to the existing vests.
within an infantry squad, at the very least, the commander and 2ic plus one more senior soldier should have comms, seeing that the Chinese squads operates in 3 groups of 3 as i understand.I'm also hoping the average infantryman at least starts getting the earpros/comms units that we see for artillery troops. They're not expensive, and if the artillerymen have it, I don't see a reason not to give them to the average infantryman.
