There are some really nice Imperial Guard releases in May from Games Workshop. As well as the nice plastic Valkyrie, one other release is looking like a possible purchase, the Imperial Guard Regimental Advisors.
The commander of an Imperial Guard army is assisted by a host of orderlies, adjutants, aides de camps and specialist advisors from outside the regiment who are able to liaise with other elements of the battle group.
This blister contains three metal Imperial Guard Advisors, including: an Officer of the Fleet, a Master of Ordinance and an Astropath.
I am thinking they might make good characters for the Warhammer 40K role-playing game or as part of an Inquisitorial retinue.
