Not just the USFS. The Michigan DNR Forest Management Division, where I work, has used 70mm color IR film in a pair of Rollei 6003's for over ten years. Unforunately Kodak has seen fit to discontinue the 70mm version of CIR, but they still make it in the 9" X 9". format. While digi CIR is pretty good, it can't hold a candle to a 9" X 9" color infrared contact print.
