According to the revealed information, at least three armor vehicle drivers in the ZBD-04A, they have QBZ95B-1 carbine and QSZ92 pistol as their PDW. So this Squad has around nine soilders.That is a surprisingly heavily equipped squad in terms of LSW/HBAR.
Two QJB-95s as we can see, and one QBU-191 (which is a DMR but also an HBAR), for three out of the six dismounts visible.
I can't recall how many dismounts a ZBD04A has, or if this squad is representative of an actual operational TOE. Interesting either way.
