This second 2-man set has a kneeling trooper armed with an M16 fitted with the M203 Grenade Launcher. He’s also wearing the locally-made ‘Tiger Stripes’ and has the special webbing pouches that carry extra M203 rounds.
The other SAS trooper, wearing the ERDL camouflage is carrying the British-made Sterling sub machine gun with the 30 round curved magazine. Both the Australian and New Zealand Armies tested out this weapon but only the Kiwis purchased it... So, chances are this particular SAS Trooper is a ‘Kiwi’.
