This pair of 28mm scale metal Uruk-hai were manufactured by "Games Workshop", and could be bought as part of their Uruk-hai Command and Uruk-hai Warriors randomly populated blisters respectively. Disappointingly, neither figure now appears to be available as part of the Nottingham-based company's current "The Lord Of The Rings" range for the Forces of Isengard, and were actually purchased in various states of disrepair second-hand at a gaming show or two many moons ago.
In order to eradicate its previous partial paint-job the Uruk-hai Captain was first treated to a couple of layers of "Citadel" Abaddon Black, before being given a coat of "Scale 75" Decayed Metal. This "Metal N' Alchemy" water-based acrylic was then dry-brushed with "Scale 75" Thrash Metal, shaded with plenty of "Citadel" Nuln Oil, and given a second, much lighter dry-brush of (more) "Scale 75" Thrash Metal.
Having reasonably replicated the old OOP "Citadel" Tin Bitz colour scheme I used on my decade-old, modestly-sized Forces of Isengard army I attempted something similar with the brutal warrior's flesh by applying a combination of "Vallejo" Heavy Red and "The Army Painter" Strong Tone Quickshade to his arms, legs, and chin. I also 'picked' out the soldier's loincloth, hair and gloves with "Vallejo" Heavy Sienna and (more) "The Army Painter" Strong Tone Quickshade.
The Uruk-hai Warrior was painted in a very similar way, albeit I had apparently already pigmented the Isengarder's armour, sword and shield ten years ago. However, as this particular minion of Saruman was actually going to be a Uruk-hai Scout Captain in my army for the "Middle-Earth Strategy Battle Game", I free-handed a rough replica of the White Wizard's emblem upon his shield in "Vallejo" White, and then weathered it with a quick dry-brush of "Scale 75" Thrash Metal.
In addition, it appears that I probably bought this model without its metal tab, and had resultantly propped the figure up on its circular base using the odd piece of plastic sprue and some metal shavings. I therefore pigmented these parts to resemble stone, courtesy of a "Vallejo" Heavy Bluegrey undercoat, a splash of "Citadel" Nuln Oil, and a careful dry-brush of (more) "Vallejo" Heavy Bluegrey.
Sticking with J.R.R. Tolkein's Middle Earth, but moving across to "Crooked Dice Game Design Studio", I have also found the time to do some groundwork on their recently-released Treant miniature. This multi-part resin kin has been assembled, pinned, primed, shaded and repeatedly dry-brushed in preparation for the 72mm tall model's leafy detail to all be 'picked out'...
