Brigadier Lethbridge-Stewart was one of the founders of UNIT and commander of its UK operations. From his second incarnation onwards, notwithstanding some early tension between the two at the start of his third incarnation, the Doctor long considered the Brigadier one of his most trusted human allies and closest friends, having encountered him in all of his incarnations, with the exceptions of his ninth and eleventh.
A slightly older Brigadier, which is more like the metal model.
Back in the 1990s Harlequin Miniatures produced a licensed range of 28mm metal miniatures. one of the blisters I did manage to get was The Brigadier.
The Brig was then given a white undercoat.
I painted the flesh tones with Citadel Elf Flesh and filled in the gaps in the base with Green Stuff.
I painted his uniform with Flames of War English Uniform 921.
Though it has been pointed out to me that the sweater would be olive green not khaki.
