effective strength; current strength
Refers to the actual, currently available strength or force of a military unit, organization, or group, as opposed to its nominal or authorized strength.
The unit's effective strength was only 60% of its authorized complement.
Accurately grasping the current strength is the first step in operational planning.
Compound of 現有 (げんゆう, 'currently possessed') and 勢力 (せいりょく, 'strength, influence'). The term is used primarily in military and organizational contexts.
