Platoons, Brigades, Divisions Oh My!

Here is a general descriptor of how the army is structured. Don't get too caught in the numbers though. Sections will vary in size. Platoons may be short sections (or may have extra sections). Regular Force infantry battalions only have three rifle companies these days (as opposed to the traditional four) and many reserve regiments only have one company.

Note that generally the "rule of three" gives you a rough estimate of what an element can be broken down in to (ie: 3 sections to a platoon, 3 platoons to a company, 3 companies to a battalion, etc, etc). However, that rule of three typically breaks down when you try to apply it to support elements or combined arms groups.

The dot/line/x system is the NATO standard designation used in conjuction with map symbols.

.. - Section

A section normally numbers about 8-10 men and is commanded by a Sgt with a MCpl as second in command.

... - Platoon or Troop

A platoon is a basic building block of sub-unit organizations. They are headed by a junior officer (2Lt to Capt) and number about 30 to 45 members. They consist of 3 or 4 sections (depending on the Arm). A Tank Troop would consist of 4 battle tanks.

ll - Batallion

As for the Infantry Battalion structure, it's usually 3 to 4 rifle companies in addition to combat support company which used to comprise of 1 x mortar platoon, 1x Recce Platoon, 1 x Anti-Armour Platoon, 1 x Pioneer Platoon (things like mortars and pioneers have been phased out of the current structure). There's also a HQ company which has a Battalion CP, Int Detachment, MP Detachment and a Sigs Platoon. There's a Logistical Company comprising of Battalion stores, payroll, maintenance, cooks and the like.

lll - Regiment

Common for Soviet and WWII German forces in which a Regiment was a fighting formation. A Regiment typically consists of three to four battalions under the command of a Col.

(This should not be confused with the term "regiment" as it is used in commonwealth armies. Those Canadian regiments which are larger than one unit are still not formations. PPCLI, RCR, R22R, RNBR, etc will never deploy under a regimental headquarters. They will always be battalions as part of a Bde. For this reason you won't see Canadian units marked as Regiments on a map. The same is true of most of our allies.)

x - Brigade

A Brigade typically consists of three to four battalions under the command of a BGen.

In Canada we have Brigade Groups, which are slightly larger than brigades, and are composed of the following:

• 1x Headquarters / Signal Squadron
• 3 x Inf Battalions
• 1x Armoured Regiment
• 1x Field Artillery Regiment
• 1x Engineer Regiment
• 1x Service Battalion (but technically not part of the Bde)
• 1x Field Ambulance unit (but technically not part of the Bde)
• 1x Military Police platoon

(The term Brigade Group is often used to designate a combined arms Brigade. These formations do not require a divisional support structure, and can be fought independent of a higher formation.)

xx - Division

2-3 brigades, commanded by a Major General

xxx - Corps

2+ divisions, commanded by a Lieutenant General
