Nicely done!!! YAT-YAS!
"I1" of "I/3/4" was MY tractor for OIF I in 2003. She was fresh off the MPF and looked brand new for the first several days in Kuwait. I was section leader and spent the drive to Baghdad in the turret. "Mad-Movie-Maloney" (aka MoDog) was my driver and "Blue-Flamer-Ledford" was my rear crewman. She made it from Kuwait to Baghdad and finally back to Adwaniyah for turnover back to the MPF vessels.
I had a horseshoe mounted to the bow of each AAV in my section. I also strapped 2 track blocks to outboard side of the turret.
As far as antennas, there should be 5. Two on the aft mounts and one on each of the side mounts. There is(was) an antenna for each radio. There is also an EPLRS antenna on the port aft just forward of the SINCGARS antenna. Like you stated, the radios are not really visible through the hatches and it would take someone that knows where and what to look for to spot their absence.
Shot of my tractor and another with myself and crew. Before we painted the unit symbol and 3/4's bull & pagoda.
