Major is a junior officer rank in the Sri Lanka Army. The rank insignia for a major is the Sri Lankan emblem. It ranks below lieutenant colonel and above captain. The equivalent is Lieutenant-Commander in the Sri Lanka Navy and Squadron Leader in the Sri Lanka Air Force.
From 1949 to 1972, in the Ceylon Army the rank insignia for a major was a crown, similar to that of the British Army Major.
A major of the Sri Lanka Army would usually commanding independent companies, squadrons and batteries, but those that were organically part of a regiment or battalion were still usually commanded by captains. They would be second-in-command of battalions in infantry or regiments (in the artillery and armoured regiments) as well as serve as Brigade majors. During the Sri Lankan Civil War majors commanded area commands known as military sectors and have commanded battalions in combat.
In 1947, at its formation the uniform of the Serjeant-at-arms of the Sri Lankan Parliament was molded on uniforms of a major.
