CIS (Junior Term) Flashcards
What is a radio station?
A set of equipment necessary to carry out communications via radio waves.
What equipment does this typically consist of? (3 Items)
Receiver, Transmitter, Antenna.
What are the two types of radio station?
Control Station
Sub Station
What is a radio net?
A group of radio stations operating on a common network.
What are the three types of radio net?
Simple Net
Combined Net
Radio Rebroadcast
Can radio net types be changed? If so, Why?
Yes. To make sure they are the most capable for the operation.
What are the key properties of a simple net?
Control station
2 or more sub stations
Common fixed frequency or group of frequencies
What are the key properties of a combined net?
Two or more nets of which normally operate separately
Joined together on a common frequency or group of frequencies.
So all stations can communicate together
What does a radio rebroadcast do?
It extends the range that which radios can communicate, typically from 30km to 60km
It joins two or more individual nets
What does SAD mean?
Security, Accuracy, Discipline
What does the Bowman have in it to ensure that it is secure?
A cryptographic material film. It is permanently embedded in the radio until removed by user.
What are the classifications for:
Non-crypto documentation/radio/info?
Crypto documentation/radio/info?
Restricted (Non Crypto)
Secret (Crypto)
If we didn’t have security measures, what would the enemy be able to discover?
Combat effectiveness
Order of Battle (ORBAT)
Intentions
Locations
Relating to transmission security, what methods do the enemy use to find information about friendly forces?
Interception
Analysis
Deception
What is interception?
Searching for, listening to and recording radio comms and electronic devices to obtain information.
What defences do we use to protect ourselves from interception?
Radio Silence Electronic Silence Avoiding Unnecessary Transmissions Keeping transmissions under 20 seconds Alternative means of communication
What is analysis?
Examination or interpretation of intercepted radio communications traffic and electronic transmissions to gain information.
What defences do we use to protect ourselves from analysis?
Calling and Answering
Callsign omission
Plain Language
What is deception?
Sending false transmissions over a communications system with the intention to deceive or create confusion.
What defences to we use to protect ourselves from deception?
Authentication
Good procedures
Constant vigilance
What aides to security do we have?
Low level codes and battlefield code (BATCO) Authentication (Using CEI) Emergency Purge (E-Purge) Security of landline and VEDs Protection of fibre optic cable
Why do the Army have a voice procedure for radio communications?
To provide the fastest and most accurate method of speech during transmissions.
What are the 4 key areas to method of speech?
Rhythm, Speed, Voice, Pitch
How are letters pronounced over the radio?
Using the phonetic alphabet
How are numbers pronounced over the radio during satisfactory conditions?
Normally - 14 is “fourteen”
How are numbers pronounced over the radio during difficult conditions
Seperate digits - 14 is “One Four”
What is brevity?
The concise and exact use of words: ie, Abbreviations, Pro-words, Punctuation
What does URAMULE stand for (unfinished)?
U - Use voice procedure R - Release presses switch promptly A- Answer calls in correct order without delay M U L E
What 7 things should NEVER be done during radio communication?
- Violate radio silence
- Compromise classified information
- Speak faster than a station experiencing the worst conditions would understand
- Make unnecessary or unduly long messages
- Identify unit by name
- Lose temper or swear
- Engage in unofficial conversation
