Training with the HK MP-5A3 "Navy Model" as used by the US Navy SEALs (with the additional of an IR laser mounted above the muzzle), on the HK Tactical Submachine Gun Course in Virginia.
HK MP-5's converted for Simunitions force-on-force training. If you can afford it, I highly recommend training with "Sims", there is no equal. If you take a closer look, you will see the red-tipped rounds in the spare-magazine.
Posing here in the universal shooting platform with the HK UMP-45 .45ACP submachine-gun with sound-suppressor attached.
