The battalion or regiment also provides the command and staff element of a battlegroup, which is complemented with an appropriate mix of armour, infantry, and support personnel and weaponry relevant to the task it is expected to perform.
Typically, an offensive battlegroup may be structured around an armoured regiment, with two squadrons of main battle tanks supported by an infantry company; conversely, a more defensive battlegroup may be structured around an infantry battalion, with two companies and an armoured squadron.
India, with the adoption of the Cold Start Doctrine, has come up with independent brigade groups a little larger in composition than a task force.
Offensive elements comprise independent armed brigade groups (usually composed of armour units) and independent offensive brigade groups (usually composed of infantry); the Indian Army has substantially reduced the time it took to deploy its forces on its borders.
In the British Army, an armoured or mechanised division could expect to have as many as twelve separate battlegroups at its disposal, with three or four in each brigade.
