Ok ok.. what about
aged camouflage?
Since Darwin was bombed in WWII the Australian Army has defended this north end weak link [shhhh] with a bunch of guys in their own personal troopy loaded with machine guns. I'm sure there's a bit more to it than that - though a bunch of Aussie diggers defending their own HJ47 with a .50cal would probably do more damage than an entire regiment defending something far less valuable like the coastline
I digress again..
Here are some pics of camouflaged Aussie Norforce troopies. If I still have a say I vote for the low-key, subtle camo, sprayed by the whole fam after a quick meeting to nail down the pattern/colours. Rattle can heaven.
