SPECIAL NCS TASKS
Definition of Special NCS Tasks
There are five tasks categorized as special for SINCGARS NCS

personnel. These five tasks enable a SINCGARS NCS to electronically
transfer FH data (to include a TSK), SOI information, and COMSEC
keys (TEK only).
The preferred method of updating these categories of data is by
physical connection of ANCD to ANCD. When the tactical situation
makes physical transfer impossible or impractical, these electronic
transfer means may be used.
All SINCGARS NCS personnel should receive at least familiarization
In units which anticipate frequent
training in these tasks.
mission-related requirements for electronic data transfer, NCS
operators should be trained to proficiency. In that many units will but
rarely have a need to use electronic data transfer, the assistance of the
Signal Offrcer/NCOs may be required for their NCSs to perform these
Summary of Special NCS Tasks
Transfer Updated FH Data via Net Update ERF
SPECIAL NCS TASK 1:
Used for electronic transfer of FH data (hopset, net ID, TSK) from one
location to another, Net update ERF may also include a change in sync
time if desired.
Transmit SOI information Using the Broadcast Mode
SPECIAL NCS TASK 2:
This IS the procedure used for electronic transfer of SOI information
from one location to another. Because of the time required to transfer
SOI data by Broadcast, each transmission is normally limited to one
Send TEK to Other NCSs Using the MK Method of OTAR
SPECIAL NCS TASK 3:
This is the principal method of electronically transferring a TEK from
one location to another. The MK (manual key) procedure moves TEK
from a Source ANCD, through the Source NCS RT through the Target
NCS RT, into the Target NCS's ANCD.
Send TEK to Net Operators Using the AK Method of OTAR
SPECIAL NCS TASK 4:
This is a method for disseminating a new TEK by electronic transfer
with a net. The procedure moves the new TEK from the NCS's ANCD,
through the NCS's radio, directly into the radios of net operators.
Receive and Store TEK Sent by MK Method of OTAR
SPECIAL NCS TASK 5:
This is the procedure followed by Target NCSs when a Source NCS
sends a TEK by MK OTAR (Special NCS Task 3, above). This task
enables the receiving NCSs to store the electronically transmitted TEK
in an ANCD, where it IS readily available for further distribution within the
unit when required.
