Preface

TM 4-48.08/TO 13C7-2-491 is a doctrine based departmental publication that provides information on how to prepare and rig loads for airborne operations. This manual provides rigging instructions for most circumstances, but it is not a substitute for sound judgement. Mission requirements may require modification of the procedures, such as variations in the accompanying load.

The principal audience for TM 4-48.08/TO 13C7-2-491 is all members of the aerial delivery community.

Commanders and staffs of Army, Marine Corps, Navy, and Air Force headquarters serving as joint task force or multinational headquarters should also refer to applicable joint or multinational doctrine concerning the range of military operations and joint or multinational forces. Trainers and educators throughout the Department of Defense will also use this publication.

Commanders, staffs, and subordinates ensure that their decisions and actions comply with applicable United States, international, and in some cases host-nation laws and regulations. Commanders at all levels ensure that their personnel operate in accordance with the law of war and the rules of engagement.

TM 4-48.08/TO 13C7-2-491 does not implement any STANAGs.

TM 4-48.08/TO 13C7-2-491 uses joint terms where applicable. Selected joint and Army terms and definitions appear in both the glossary and the text. Terms for which TM 4-48.08/TO 13C7-2-491 is the proponent publication (the authority) are italicized in the text and are marked with an asterisk (*) in the glossary.

For other definitions shown in the text, the term is italicized and the number of the proponent publication follows the definition.

The following definitions apply to “Danger,” “Warning,” and “Caution” found throughout the manual.
