The basic Brotherhood unit is the Regiment. It is based upon an equivalent 5,000 man Imperial Guard regiment. Why change such a winning setup?

1. Command (approx. 200 men)

1.0 Regimental HQ (approx. 50 men)

1.1 Recon - Scout Platoon (approx. 50 men)

1.2 Comms - Vox-signals Platoon (approx. 50 men)

1.3 Engineering Platoon (approx. 50 men)

3. 1st Infantry Battalion (approx. 900 men).

3.1. Rifle Company (approx. 225 men)

3.2. Rifle Company (approx. 225 men)

3.3 Rifle Company (approx. 225 men)

3.4 Heavy Weapons Company (approx. 225 men)

4. 2nd Infantry Battalion (approx. 900 men).

6. 4th Infantry Battalion (approx. 900 men).

7. Support Battalion (approx. 750 men)

8.1 Transportation Company (approx. 200 men)

8.2. Tech-support Platoon (approx. 50 men)

The basic unit is the Rifle squad, made up of about 10 men, led by a Brotherhood Sergeant. They are armed with lasguns and/or autoguns, plus whatever heavy and specialist weapons they can get their hands on. Squads are organized into platoons. Platoons into Companies. Companies usually have a special weapons and/or HW platoon. The HW company has many more such weapons, plus mortars and the like.

The Tank company is (ideally) made up of 14-18 tanks, preferably Leman Russ or the equivalent, but most companies have less tanks and/or inferior vehicles (it's not unnusal to find Chimaeras fielded as tanks for example; hopefully this will improve in the future).

The Support Battalion has 2 artillery coys (14-18 basilisks per unit would be nice, but it's going to be a while before that become a reality), 1 AT coy (missile launchers and lascannon for the most part), 1 AAA platoon (more ofthe same, but with AAA sights/mounts).

---

Mechanized: Largely the same, but infantry is mounted on AFVS. Reduce Infantry Regiments by 1, but increase Armoured Coy to full Battalion. Larger transportation and tech-support.

Armoured: As Mechanized, but 1 of 3 Infantry regiments become Armoured (for a total of 2 and 2).

Elite Drop: Same as (Light) Infantry, but with access to light vehicles and drop-/gunships.
