13th Armored Cavalry Regiment

[ArmySGT.]

A Regiment is equivalent to a Brigade..... a little smaller with less support units.

The British Army uses the Regimental system, the U.S. Army abandoned the Regimental system with the Pentomic army structure.

Regimental titles exist but, as a structure not any longer.

*edit* I forgot to add........Regiments are pure...... A Infantry Regiment is just that..... 3-5 Battalions of Infantry. Artillery same. Cavalry same. It was part of the style of the times.

Now with combined arms thinking........ Pure stops at the Battalion level, and Brigades are built of Battalions tasked to missions.
