Jagu

Jagu, (Squad) is a small military unit led by a non-commissioned officer (NCO) that is subordinate to an infantry platoon. Jagu is bigger than a salk (fireteam) but smaller than a rühm (platoon). It is also one of the smallest military formation among the Estonian Ground Force infantry units.

Leadership
It usually consists six to ten soldiers, and may be further subdivided into fireteams. A jagu is composed of two fireteams of five soldiers each, as well as a squad leader (jaopealik) who is usually a sergeant (seersant). His second in command is known as a squad sergeant (jaopealiku abi).

Organization
One single jagu is meant to operate on a battlefield along with other jagu's on a landscale not greater than 100 x 200 metres. There are no logistical support elements in the structure of a jagu. The formation transport is usually made up by one tactical transport vehicle such as Mercedes-Benz UNIMOG 435.

Other military uses
A squad can also be an ad hoc group of soldiers assigned to a task, for example, a firing squad. In the Canadian Army, the term "squad" can actually refer to a portion of a drill movement. This is generally used when a group of soldiers is learning a new drill movement, as it is easier to learn step-by-step, rather than all at once.
