The branches of the armed forces of Bhutan are the Royal Bhutan Army, Royal Bodyguards, Militia and Royal Bhutan Police. Membership is voluntary, and the minimum age for recruitment is 18. The standing army numbers about 16,000 and is trained by the Indian Army.
Being a landlocked country, Bhutan doesn't have a navy. Additionally, Bhutan does not have an air force, although the Royal Bhutan Army does have a very small air arm which possesses no combat capabilities and is used entirely for transport.
India is responsible for military training, arms supplies and the air defence of Bhutan. The Royal Bhutan Army relies on the Eastern Air Command of the Indian Air Force for air assistance.
