I used Mofo Falklands War Brits, with some Mongrel BAOR mixed in... I used some helmets to mix it up and figured they'd be like today's UN troops and have the helmet painted to match the beret.




I used Tamiya Nato Green throughout, with GW Snakebite Leather for the berets...
In the show, UNIT started out with futuristic uniforms in beige, but soon ended up with standard British Army kit. The special edition of Day of the Daleks, does have them in camo, and it's been a while, but think there were other instances of them in camo, but on the whole just olive drab will do it.
