It is built using the Dragon M270A1 kit. I also added PE for the radiator grill, engine intake, and a few other pieces from the Royal Model MLRS detail set. I replaced the older, triangle block tracks with a set of newer, square block, indi-link tracks from the Meng M2A3 kit. I also added the GPS antenna on top of the launcher box (green square). The M26 rocket emerging is a rocket from the Dragon Patriot PAC 3 set. They happen to be the same basic size and look close enough. The storage box on top is scratch-built from bass wood sheet.
Most of the decals were made by me on computer decal paper. I also used a few smaller ones from an Echelon kit and the older Dragon M270 kit.
Here it is. Sorry, I didn't take any in-progress pics.
