Town Control

[Greyfox]

Control is a tactical mission task that requires the commander to maintain physical influence over a specified area to prevent its use by an enemy or to create conditions necessary for successful friendly operations.


This is straight out of U.S. Army Doctrine which hasn’t changed much in my almost 27 years of affiliation. This supports your number 1 as the requirement for the attacker which means defender needs to meet criteria number 3 to achieve his objectives.

Hope this helps.
