INTRODUCTION
1.
The facsimile allows electronic transmission of text and graphic information between remote and
centralized military communications facilities. The graphic materials consist of maps, photographs, line
drawings, printed or typed materials, or hand-written messages. Such items are sent in whole or in part.
Before the facsimile, messages went through many hands from the writer to the reader. The more hands,
the longer the delays before the information in the message could be used. Graphic type materials had
to be sent by courier, taking more time. The facsimile operates in a military environment using the wide
range of communications links available to the various levels of command. User-owned and -operated
facsimile reduces the time required to provide the user with information that is vital to the mission. A
permanent pictorial copy, record copy, of the original message is copied for the user. The delivery of a
permanent copy is a distinguishing feature of the facsimile. This differs from television which is viewed
at the instant of reception or not at all. Facsimile equipment is assigned to using units as shown below:
a. Facsimile equipment is used in EAC communications centers for the passing of graphics
traffic and the conversion between two record traffic systems (teletypewriter/facsimile/teletypewriter).
b. Facsimile equipment is used by all headquarters elements, battalion through corps, and
selected units with a record/graphics traffic requirement.
