Battle tanks are tracked armoured fighting vehicles which weigh at least 16.5 metric tonnes unladen weight and which are armed with a 360-degree traverse gun of at least 75 millimetres calibre. In addition, any wheeled armoured fighting vehicles entering into service which meet all the other criteria stated above shall also be deemed battle tanks.

In addition, any future large calibre direct fire system which has a secondary effective indirect fire capability shall be counted against the artillery ceilings.

The term "attack helicopter" comprises specialised attack helicopters and multi-purpose attack helicopters.
(N) The term "specialised attack helicopter" means an attack helicopter that is designed primarily to employ guided weapons.
(O) The term "multi-purpose attack helicopter" means an attack helicopter designed to perform multiple military functions and equipped to employ guided weapons.
(P) The term "combat support helicopter" means a combat helicopter which does not fulfill the requirements to qualify as an attack helicopter and which may be equipped with a variety of self-defence and area suppression weapons, such as guns, cannons and unguided rockets, bombs or cluster bombs, or which may be equipped to perform other military functions.

Taking into account the provisions of the Geneva Convention "For the Amelioration of the Conditions of the Wounded and Sick in Armed Forces in the Field" of 12 August 1949 that confer a special status on ambulances, armoured personnel carrier ambulances shall not be deemed armoured combat vehicles or armoured personnel carrier look-alikes.
