This post doesn't have anything to do with Steve Jackson Games' current moratorium on the sale of OGRE/GEV minis. Instead, it's a look back to the halcyon days of this line of miniatures, when boxed sets sold for under $20 retail.
Opening up my set of Paneuropean Infantry from the early 2000s, I found a checklist for all the planned OGRE Miniatures boxed sets. As you can see, in addition to the North American Combine and PE starter sets, SJG sold twelve boxed sets of NAC minis and ten sets of PE castings.
Wave One minis reprint that was a Kickstarter goal), those from Combine Set 9: Laser Towers and Turrets were not available until the recent Ogre Minis Wave Two reprint. And a couple of these boxes, Combine Set 8: Divisional Assets, and Paneuropean Set 9: Laser Towers and Turrets, were never even produced (although the Combine structures and the Paneuropean lasers eventually appeared last year with Wave Two).
I think such a vehicle would contribute to an interesting game. The problem is finding a miniature to represent it. This thread on The Miniatures Page has several suggestions, including using die-cast toys. I think that's the route I'll go, if I decide to use a GEV mobile command post in a game of OGRE.
