===== Heavy Mobility Infantry Company =====
Each company is commanded by a Major with a senior((i.e. one on a second or subsequent tour rather than an actual rank)) Captain as his second in command. The basis of the company is the four person fire team, commonly called a brick. 

Each brick can operate independently if it has to for a short period of time. Every brick has an officer or NCO in it plus junior NCO as the second in command of the brick.

There are 23 bricks in a Heavy Mobility Armour (HMA) Infantry Company. This gives 92 effective soldiers. Organisationally these are structured as follows:

==== Company HQ Section ====
  - Major (officer commanding) [0 on company net], Sergeant Major, 2 x Soldiers
  - Captain (2ic), Lieutenant((a senior Lt who can act as a battle casualty replacement for either a platoon or section commander)), 2 x soldiers (all four are SLA3 armed)

==== 1 Platoon ====
=== Platoon HQ Section ===
  - Captain (comd), Platoon Sergeant((this is a rank between Sergeant and Lieutenant, often filled by officer candidates before commissioning)), 2 x Soldier

=== 3 x Sections ===
  - Lieutentant (Sect comd), Corporal, 2 x Soldier
  - Sergeant, Lance Corporal, Soldier, SLA3 armed Soldier

The remaining two platoons are structured in the same way as the first platoon. On the company net each platoon is distinguished by a colour or letter in front of their numerical call sign. The practice varies from company to company and on active operations the companies may well change their comms designation on a frequent and regular basis.
