Army Field Manual FM 3-34 (Topographic Surveying)

"This FM is a guide for military occupational specialty (MOS) 82D (Topographic Surveyor). It provides techniques not found in any commercial text concerning the precise determination of position, azimuth, or elevation of a point. Additionally, this publication describes and standardizes procedures for performing recons, preparing station descriptions, and reporting and briefing survey projects. The material in this manual is applicable, without modification, to all geodetic survey projects in all environments (pre-battle, conventional war [nuclear and non-nuclear], low intensity conflicts, and post-battle). The contents comply with Army doctrine and international precision surveying doctrine or theory and may be supplemented with commercially available texts or previous editions of technical literature."-From the Preface.
