CHAPTER II
MILITARY COMMUNICATIONS
The following are the various types of military communication:
Field messages convey verbal or written information by messenger or wire.
Reports are written accounts of some enterprise, undertaking, or event, such as a reconnaissance, march, or battle.
War diaries are daily records of events kept during campaign by each battalion and higher organization. From the entries in these diaries the facts of our military history are obtained.
Letters of instruction, issued by higher commanders, regulate in a general way movements covering much time and space. Army and Corps commanders may, by visits and conferences, often communicate verbally the substance of letters of instruction.
