This volume is the fourth in a series of books that Battles & Book Reviews Publishing is releasing that encompass reprints of public domain US Military manuals that are useful to the prepping community. This book contains the full text and images contained within the April 2003 version of Field manual 5-34 Engineer Field Data. This manual is packed with useful data tables on just about every aspect of military operations. It was one of my go-to manuals during my own military career and I always had a copy in the turret of my Bradley behind the coax ready box so I could get to it without digging when I needed it.
