Physics types worked with sound and flight paths to determine a good number of things. Communications and medical advances also were pushed. As a result command after this determined that those types had more value behind the lines, no matter what they wanted to do. (If I remember right Mosely was quite a patriot, but it is a bit foggy, I also think there might have been a similar Russian story). Anyway, we all know this was further legislated by the time of WWII when science around the bomb and other things became highly classified and structured around service to the government by these means. They also encouraged or at times even pushed hard farmers to stay on farms rather than join the service. Nice to catch up with you a bit--gotta go pick my youngest up from preschool.
