What ink color is required for entries in the weapons log book?

• A. Purple
• B. Red
• C. Black or blue
• D. Green

Answer: (C)

Official log entries must be written with ink that stays legible over time and reproduces well in copies and archival records. Black ink provides the highest contrast on white pages, making entries easy to read and hard to alter; blue ink is also acceptable as a clear, official alternative. Red ink is typically reserved for corrections, endorsements, or warnings, not for the initial recording of entries, which is why it isn’t appropriate here. Purple and green inks aren’t standard for formal logs and may not reproduce reliably, so they’re not used for weapons log entries.
