Defense Military Tactical Communication 2 — Questions and Answers
Question 1: What does the proword 'WILCO' mean in military radio communications?
- Message received and understood
- Will comply with instructions received (Correct answer)
- Waiting for confirmation
- Wrong channel detected
Correct answer: Will comply with instructions received
WILCO means 'I have received your message, understand it, and will comply' — it implies ROGER, so both are never used together.
Question 2: Which frequency band is most commonly used for line-of-sight tactical ground communications in the U.S. military?
- HF (3–30 MHz)
- VHF (30–300 MHz) (Correct answer)
- EHF (30–300 GHz)
- LF (30–300 kHz)
Correct answer: VHF (30–300 MHz)
VHF is standard for short-range line-of-sight tactical communications between ground units.
Question 3: In the NATO phonetic alphabet, which word represents the letter 'N'?

Correct answer: November
November is the NATO phonetic alphabet word for the letter N.
Question 4: What is 'EMCON' in military communications?
- Emergency communications protocol
- Emissions control to limit electronic signatures (Correct answer)
- Encrypted message control
- Extended mission communications network
Correct answer: Emissions control to limit electronic signatures
EMCON (Emissions Control) is a procedure restricting or eliminating electromagnetic emissions to reduce detection by enemy forces.
Question 5: A unit receives a FRAGORD. What type of communication does this represent?
- A full operations order replacing the previous OPORD
- A fragmentary order modifying an existing OPORD (Correct answer)

Correct answer: A fragmentary order modifying an existing OPORD
A FRAGORD (Fragmentary Order) modifies or supplements an existing OPORD without re-issuing the entire order.
Question 6: What is the purpose of using 'brevity codes' in tactical air-to-air communications?
- To encrypt messages from enemy intercept
- To relay standard messages quickly and reduce radio time (Correct answer)
- To authenticate pilot identity
- To switch communication frequencies automatically
Correct answer: To relay standard messages quickly and reduce radio time
Brevity codes standardize common messages into single words, reducing transmission time and radio clutter in high-tempo air operations.
Question 7: When establishing a radio net, which station is responsible for controlling communications traffic on the net?
- The relay station
- The net control station (NCS) (Correct answer)
- The forward observer station
