Which color combination identifies incendiary rounds?

• A. Red with blue ring
• B. Orange with white ring
• C. Blue with yellow ring
• D. Dark blue with light blue ring

Answer: (D)

Color coding on ammunition uses body color plus a ring to signal the type of round at a glance. For incendiary rounds, the recognized marking in this system is a dark blue body with a light blue ring. That combination provides a distinct, quick cue so handlers know the payload is incendiary and handle it accordingly. The other color patterns don’t match this incendiary marker, so they’d be interpreted as different types of rounds. Keep in mind that color codes can vary by country and era, but within this framework, dark blue with a light blue ring identifies incendiary rounds.
