day we have another first: The first two FMs exclusively available on this site, contributed by a reader! We are very grateful for Scott to have scanned FM 5-31 Use and Installation of Boobytraps (1956) and FM 21-50 Ranger Training and Ranger Operations (1962) from our Missing list, and provided the scans to us. We reduced the resolution of the scans in order to scale them down to a web-friendly sice, but the quality is still way better than most of the MHI-scans of older manuals. So a very big thanks to Scott, and you*ll find both manuals in their respective sections, or with the links above.
