Military Organizational Strength Hierarchy - Detailed from Largest to Smallest


The sheer size of modern armies dictate the need for efficient organization of the fighting forces.

General force structure and applicable strengths are listed below from largest to smallest. The largest field component is the Region / Theater Army which can include upwards of 640,000 men (4+ Army Groups). The smallest field component (beyond an individual soldier) is the fireteam which can be comprised of three to four personnel. In-between are the well known designations (in descending order) of Corps, Division, Regiment, Battalion, Company and Platoon.

NOTES: The term 'men' is used in the generic sense in the fields below; the values listed are approximations as each national army can have different definitions on particular component force strength.
