This volume is the second 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 August 1968 version of Field manual 5-15: Field Fortifications. This is an older manual that was superseded in the early 1980's by two manuals FM 5-102 Countermobility and FM 5-103 Survivability. These two successor manuals are much more concentrated on planning factors for engineers and less so on the nuts and bolts of actually building and emplacing field fortifications.

I will release these two manuals as hardcopies also at some future time but I wanted to get this manual out there sooner since it is full of more immediately practical information than either 5-102 or 5-103, which are written much more as planning manuals than something you pull out in the field to find practical information on what you need to build a specific obstacle and/or fortification. The contents of this volume are a faithful, cleaned up edition of this manual that has been formatted to fit the paper size. Further volumes in this series are forthcoming
