For your information and concurrence, I have outlined below
the routine procedures for handling incoming classified teletype messages in the forward area:
a. The documentation of teletype messages from the States
received at this Headauarters will vary, depending upon the time of
arrival of the message.
b. Incoming teletype messages are received in three (3) copies
during duty hours (0730 hours to 1715 hours) and in two (2) copies during non-duty hours (1715 hours to 0730 hours). Classified messages are
documented in accordance with the series assignment given in the message.
If such assignment is not presented in the message the primary addressee
ie assumed to be series "C" and each subsequent addressee is assumed to
be series "D", "E", SF", ete., according to his position on the list of
addressees.
The originator is not notified as to whether two (2) or
three (3) copies were received at this office and he is not notified of
distribution of conies within Task Group 7.1.
In the event a message
is reporduced in excess of the copies received from the TWX Center, the
new copies are assigned the next series and the originator ig notified
as to the number of copies and the distribution of that series.
ec. Classified messages for personnel at Bikini are received at
Parry for retransmission. As it is not necessary to retype the message
during duty hours for retransmission to Bikini, the Bikini series is the
next letter following that of the message received on Parry.+ During nonduty hours it is necessary to reproduce the message on Parry for transmittal through the military system and therefore, the second Parry series
assumes the next letter and the Bikini series "be comes two (2) letters following the series of the original "24
