| What are the four operational principles of signal support? (para 2-1, FM 24-1) | Continuity - uninterrupted availability of information ; Security - protect signal support and support deception; Versatility - ability to adapt to unforeseen signal support; Simplicity - system must be simple to install, operate, and maintain |
| What are the five categories of signal support available to units? (para 2-3, FM 24-1) | Radio (single or multichannel), wire and cable (coaxial or fiber optics); automation (computers); visual and sound (photographs, graphic illustrations); manual (messengers) |
| What is an SOI? (para 5-6, FM 24-1) | It is a communication security (COMSEC) aid designed to provide transmission security by limiting and impairing enemy intelligence collection efforts. |
| What is the primary feature of the SOI? (para 5-6, FM 24-18) | It provides for frequent (daily) and sinultaneous changes of signal-channel FM radio call signs, suffis, and frequences. |
| What is the SOI so important? (para 5-6, FM 24-18) | It remains the best means of security for nonsecure communication |
| What are call signs? (para 5-12, FM 24-18) | Call signs are used in radio communication to identify a communication facility, a command, an authority, or a unit |
| What is the phonetic alphabet? (page 5-9, FM 24-18) | A-Alpha, B-Bravo, C-Charlie, D-Delta, E-Echo, F-Foxtrot, G-Golf, H-Hotel, I-India, J-Juliet, K-Kilo, L-Lima, M-Mike, N-November, O-Oscar, P-Papa, Q-Quebec, R-Romeo, S-Sierra, T-Tange, U-Uniform, V-Victor, W-Whiskey, X-X-ray, Y-Yankee, Z-Zulu |
| What is the phonetic numbers? (page 5-10, FM 24-18) | 0-Ze-ro, 1-Wun, 2-Too, 3-Tree, 4-Fow-er, 5-Fife, 6-Six, 7-Sev-en, 8-Ait, 9-Nin-er |
| What are the "PROWORDS"? (para 5-14, FM 24-18) | To keep voice transmission as short and clear as possible, radio operators use procedure words (PROWORDS) to take the place of long sentences. |
| What is meant by the proword "OUT" when transmitting and receiving over the radio? (page 5-13, FM 24-18) | This is the end of my transmission to you and no answer is required or expected |
| What is meant by the proword "OVER" when transmitting and receiving over the radio? (page 5-13, FM 24-18) | This is the end of my transmission to you and a response is necessary. Go ahead; transmit |
| What is meant by the proword "ROGER" when transmitting and receiving over the radio? (page 5-14, FM 24-18) | I have received your last transmission satisfactorily |
| What is meant by the proword "WILCO" when transmitting and receiving over the radio? (page 5-15, FM 24-18) | I have received your signal, understand it, and will comply. |
| Are the prowords "ROGER" and "WILCO" used together? (page 5-15, FM 24-18) | No, the meaning of "ROGER" is included in that of "WILCO". |
| What is a TA-312? (page 1-6, TC 24-24) | A battery operated field telephone |
| What is the operating range of TA-312? (page 1-6, TC 24-24) | Approximately 22 miles |
| What is the difference between communication security (COMSEC) and ECCM) (para 6-4, FM 24-18) | COMSEC is designed to increase the security of our transmissions, while ECCM ensures some degree of protection from enemy electronic-countermeasures (ECM) and electronic-warfare-support-measures (ESM) |
| What are the four types of security included in communication security (COMSEC)? (para 6-4, FM 24-18) | Emission Security - controlling electrromagnetic emission; Transmission Security - with what and how information is transmitted; Crypto Security - deals with code, key list, and COMSEC devices; Physical Security- protect your radio and related material (SOIs and key lists) |
| What does SOI stand for? (glossary-4, FM 24-18) | Signal Operation Instructions |
| What type of battery is used in the TA-312?(page 1-6, TC 24-24) | D-cell |
