Transcript Voice Procedure - A Company, Devon Army Cadet Force

Voice Procedure
 To
minimise the risks associated with
Interception, Analysis and Deception there
are a set of rules collectively known as
Voice Procedure.
Interception
 ALL
radio traffic is subject to interception
by hostile forces.
Analysis
 Intercepted
radio traffic can be analysed to
obtain useful information.
Deception
 After
analysis, the enemy can use our own
radio nets to deceive us.
 This could take the form of additional
traffic or could be even simpler such as the
use of recordings.
INTRODUCTION TO VOICE
PROCEDURE
Voice procedure is designed to provide us
with:-
Security.
Accuracy.
Discipline.
This can be remembered by the
mnemonic.
S ecurity
Accuracy
Discipline
SECURITY
By listening to our radio traffic, the
enemy will try to discover certain
information that is important to
operations.
COMBAT
EFFECTIVENESS
Casualties.
Damaged or defective equipment.
Standard of Radio discipline.
ORDER OF BATTLE
Command structure.
Radio net level, composition
and function.
Unit identities.
INTENTIONS
Tactical groupings.
Movement.
Operational plans.
LOCATIONS
Formation and unit boundaries.
Areas of operation.
Location of headquarters.
This can be remembered by the
mnemonic.
Combat effectiveness.
Order of battle.
I ntentions.
L ocations.
AIDS TO SECURITY
To assist us in keeping elements of COIL
and other information to ourselves and
not revealing them over the radio or line
we have the following aids to security:
CALLSIGNS
A callsign is a combination of letters and
figures which identify a communications
facility or an organization or a individual
on a Radio net.
ADDRESS GROUPS
A unique, daily changing group of four
random letters assigned to disguise a
command,formation, unit or sub-unit.
eg: 11SR = Address Group SMBF
NIS
Net Identification Sign
A twice daily - changing, random
2 letter group allotted to a radio net to
provide a concealed reference to the
identity of the net.
CODEWORDS
A single word with a pre-arranged
definition used to initiate a plan or
operation. Once used all of its security
value is lost and therefore it must not be
used again.
AUTHENTICATION
Authentication is a security aid designed
to protect our communications against
deception from fraudulent transmissions
from unauthorized persons.
This we will cover in a later lesson.
LOW LEVEL CODES
The code you will be using is called BATCO
(Battle Code).
Never use any unofficial codes.
This can be remembered by the
mnemonic.
Callsigns.
Address groups.
Net Identification Signs-NIS.
Codewords.
Authentication.
Low level Codes ie BATCO.

Phonetic alphabet.
Use of the proword “figures”.
Spelling.

Use of the proword
“figures”
During difficult conditions, or when
extra care is necessary to avoid
misunderstanding, figures are sent digit
by digit preceded by the proword
FIGURES.
SPELLING
Spelling is necessary when difficult
Radio conditions prevent the reception
of an obscure word, or of a word or
group which is unpronounceable. They
are preceded by the proword I SPELL.
SPEECH TECHNIQUE
Rhythm - Short sentences with a natural
rhythm.
S peed
- Slightly slower than normal
conversation.
Volume - Normal unless on “whisper”.
P itch
- Slightly higher than normal.
DISCIPLINE
The rules for Radio Discipline (1)
The following rules are mandatory on all Radio
nets where every station must:
ALWAYS:
Use correct voice procedure.
Maintain a constant listening watch.
Ensure Frequency is correct.
Answer all calls without delay.
Listen before you transmit.
Release the pressel promptly.
Ensure the Radio returns to receive.
The rules for Radio Discipline (2)
The following rules are mandatory on all Radio
nets, where every station must:
NEVER:
Violate Radio silence.
Compromise classified Information.
Make unnecessary or unduly long transmissions.
Engage in operators or unofficial conversation.
Identify yourself or unit by name.
Speak faster than the station experiencing the
worst reception can be expected to understand.
Swear or lose your temper.
THE RADIO NET
A Radio Net is a number of radio
stations grouped together on a
common frequency for the sole
purpose of communicating with
each other.
THE SIMPLE NET

There are three types of Net:
Simple nets
Combined nets

Substations
TYPES OF STATION
There are two types of radio station:
Control Station. Has the authority and the responsibility for
controlling communications, the flow of message traffic and
enforcing radio discipline.
Substations. All other stations on the net are subordinate to,
and must obey orders from, control and are known as
substations.
THE CALLSIGN
A callsign is a combination of letters and figures used to identify
a communications station, an organisation, or an individual on a
radio net

Establishing Comms
 This
is carried out by the control station
performing a “RADIO CHECK”.
 The responses to a radio check are:
 1: OK comms are satisfactory.
 2: DIFFICULT comms are not 100% but
are workable.
 3: UNWORKABLE Comms are not
possible.
ORDER OF
ANSWERING
Order of Answering

SUMMARY
 You
should now be able to:
 Understand the need for ComSec.
 Establish communications on a simple radio
net, answering in the correct order.
 Send simple messages accurately and
clearly, using correct voice procedure.
