I wasn't able to find a guide I completely liked, but I was trying to replicate the simply gorgeous paint job found here.
I used the paint colours found there, with the exception of the Dark Sand.
I actually tried three slightly different styles; the below is the scheme I followed for my favourite result.
|The figure was based with Russian Uniform and then had 'reverse patches' painted onto it with Military Green|
|Streaks - rather than patches - of English Uniform were painted on top|
|Patches of Khaki were added, then little squiggles of Iraqui Sand,trying not to overdo the latter.|
|Finally squiggles of German Camo Black Brown are added|
|Probably better seen from the rear on this figure|
The others were approached in slightly different ways.
|My commander - the first attempt - started with 'splotchier' base colour patches, and I attempted to find a place for the Dark Sand, which I think made his trousers too light.|
With my sniper, I tried a scheme reminiscent of my Flames of War Para's, in that three main camouflage colours were all painted on top of the first, which itself covered roughly 75% of the base colour.
Like I should be writing painting tutorials anyway. If you have a good tutorial for British MTP, please share it in the comments.
