Translation

大佐 / 陸軍大佐 / 軍の上級将校

Meaning

Colonel is a senior military officer rank, usually above lieutenant colonel and below general in many systems. The spelling trap is strong: colonel is pronounced like kernel, but it means an officer, not the inside of a seed.

Examples

• その大佐は記者会見で作戦を説明しました。
  The colonel explained the operation at the press conference.
• 彼女は空軍で大佐に昇進しました。
  She was promoted to colonel in the air force.
