"An entire Legion of my best men awaits them."
Back in the days when I was part of West End Games and we were developing The Imperial Sourcebook, we wanted it to be clear that the Stormtrooper Core was a distinct part of the Impeiral War Machine, separate from the armed forces of the Imperial Army and Navy.
When we listed the Stormtrooper Core's Order of Battle, we used many real world militaries as reference - from Imperial Rome's legions to World War II Wermacht formations to NATO's modern day (at the time 1990's) unit sizes.
Modern day armies are more streamlined of course, smaller fire teams of today accomplish with more efficiency and speed what much larger units of our forefathers bled for.
While I am quite proud of what we came up with for the Impeiral Sourcebook and I still use those unit numbers when I run my games, it appears Disney has now changed the Impeiral Order of Battle.
Here now is be new Canon Stormtrooper Core unit numbers.
10 Stormtroopers per squad.
5 Squads in a Platoon.
4 Platoons form a Company.
4 Companies make up a Battalion.
4 Battalions in a Regiment.
4 Regiments comprise a Legion.
12,800 Stormtroopers in an Imperial Legion.
