How many soldiers are in a divsion?

Answer 1

in an Army Division Approx. 12000-15000

Answer 2

Last time I checked, the US Army was still using the "triangular" organizational make up, so:
3 platoons make a company
3 companies make a battalion
3 battalions make a regiment
3 regiments make a division
The reason for this is the tactical doctrine of:
1 unit in reserve (to exploit a breakthrough or add strength to the defense somewhere)
1 unit to bring fire on the enemy and hold them there
1unit to flank

Typically, a US Division will have somehere between 15,000 (lean) and 40,000 (mean) individuals. Though current doctrine focuses heavily on ad-hoc or "expeditionary" units that are made up of various units of different size and specialty, so it would not be uncommon to find (in Iraq for example) an MP company mixed with an infantry battalion and a platoon of tanks or a battery of artillery in support. The reality is that division size units are becoming an operational anachronism, units of much smaller size are now far more common, some of which will even report directly to a corps, army or even theater commander. Hope this helps ;)

Answer 3

Depends on the nationality, makeup and time frame you're talking about. Soviet divisions were typically about 70% of Amercian ones. Armor divisions are typically about 5-7K bigger than light infantry ones. Also, if there are attachments to the division, they can get quite big. Armored divisions a few years ago ran about 15-20,000 but now the Army has the Unit of Action thing, instead of three brigade task forces, there are 5. I don't think it's a net gain of 2 brigades because I think they downed the combat support and combat service support elements per each division when they upped the combat arms content.

Answer 4

it varies depending on the period of history, the type of division, and the county, and the mission.
Some divisions in the Napoleonic era had only around 4000 troops.

A good rule of thumb would to consider a division in modern era to have around 10,000 troops.

Answer 5

it depends on how many assigned brigades the division has, plus you also have the separate units attached, so the numbers can vary.

Answer 6

18,000 to 20,000
