Commander-in-Chief (Army) (Burmese: ကာကွယ်ရေးဦးစီးချုပ် (ကြည်း)), is the highest ranking military officer of the Defence Services (Army) a.k.a. Myanmar Army, and the third highest in the Defence Services a.k.a. Tatmadaw. After the unification of Army, Navy, and Air Force in 1955, the Tatmadaw had the Chief of Staff system and the branches were led by Vice Chief of Staff (Army), Vice Chief of Staff (Navy), and Vice Chief of Staff (Air), respectively, until 1989. A new system was introduced in 1989 during the reorganisation and each branch is now led by its own Commander-in-Chief. Since then, except in the special case of the 26-day period in 2026, the Commander-in-Chief (Army) traditionally serves as the Deputy Commander-in-Chief of Defence Services simultaneously.
