Here's one I've done previously, to use the infamous 'Blue Peter' presenter catch-all phrase. A mixed manufacturer picture of an Esci White Scott Car (OK so there are no decals, what's new there then), part of a Hasagawa M3 Half Track and some (squad of) my Revell WW2 American Ardennes infantry. These were done as a trial batch a couple of years ago.
The plan was/is to set a factory production system and "go through the lot" (and there is an awful lot of bare green plastic) in a week. They were my first attempt at the PVA pre-coat system, but suffer methinks from too much PVA covering too much detail.
The paint scheme is taken from the back of the Revell box and is now in question. These are slightly later figures than the Valiant Miniatures 1942-44 GI but I do so like Valiant's painting guide. Also, although not a fan (or rather I am ignorant of the Flames of War system) their 'all the colours you need' US painting pack looks quite an attractive option too.
The above however will remain painted as is for posterity and more importantly are wargame ready :)
