There is a lot more to winning a battle, a campaign and a war then just simple organization… But organization helps. If you can fudge the numbers a little bit to bring a few more soldiers to the fight at every level (your squad has 10 guys instead of the enemy’s 9, your battalion has 750 guys instead of the enemy’s 700) things will work out at least mathematically… If a commander can deliver a victory is a whole other matter entirely!
Let me know what you think in the comments, and if you have any examples yourself or ones you would like to see me write about in here!

As a history guy, who doesn’t have military background but is fascinated by battle history, I have a gap in my full understanding of tactics. this short article presented an accessible and informative guide to how armies are organized and utilized. Would like to read more about how this structure has worked successfully and why other organizations haven’t worked. Thanks

Thank you for the feedback and for reading my article Paul, I really appreciate it. The themes covered in this article are recurring throughout history and I will be doing some more in depth looks at military unit organization throughout history and the why’s and how’s of the failures and successes. Stay tuned!

Where do regiments fit into this organization?

Regiments were a bit more fundamental than Brigades and Divisions, so they were not as prone to changing in manpower and organization. The Confederacy still used the Regiment as one of their basic warfighting units, while The Union relied on Brigades and Divisions much more.
