In such cases, impedimenta will be marked with the assigned shipment number and letter or other comparable code designation. The unit designation will not be used as a marking on impedimenta, although a letter or abbreviation may be used to identify the impedimenta of each element in the movement.
73. In Staging Areas:
a. Instructions will be given to all individuals concerned in the applicable security provisions in this section.

c. During the period of restriction, communication with other military personnel and civilians may be prevented or limited as may be considered necessary by the staging area, port, or airport commander concerned.
a. Unit movements will be made without attracting undue attention. Authority to use bands during embarkation of troops is left to the discretion of port commanders, where, in their opinion, the playing of a band will not jeopardize the security of the movement.

75. At Sea:
a. After sailing from the port of embarkation, the destination may be disclosed to members of units, replacements, or individuals aboard ship as necessary for training or indoctrination en route.

(5) Oversea or intertheater destination represented by a temporary APO number.
c. The provisions of paragraph 69 will apply to information concerning the oversea travel of replacements and individuals when both air and water transportation are employed.
d. Orders and allied papers for oversea travel by commercial aircraft of replacement, contingents and individuals may be unclassified, even though they contain elements of information for which a classification of CONFIDENTIAL is required by b(1), (2), (3), and (4) above.

g. The specific airport of destination within continental United States for returns to the United States by air from theaters of operation is CONFIDENTIAL information.
77. Theater of Operations in Continental United States. The foregoing paragraphs of this section are based on the assumption that theaters of operations will be located overseas. However, should any portion of continental United States become a theater of operations, the provisions of the foregoing paragraphs nevertheless will apply, subject to the following:
a. The portion so designated will be treated as an "oversea designation."
b. The terms "continental United States" and "United States" will refer only to the zone of interior.
c. The movements or travel by rail or motor from the zone of interior to the theater of operations and the security provisions applicable to ports of embarkation will apply also to points in the zone of interior from which direct movement to the theater commences, and the provisions applicable to water movement or travel will apply to land movement or travel.
