War zone

A war zone is a point in space-time in which a war or an armed conflict is occurring.

In The War Games
The War zones in the second Doctor's episode "The War Games" were eleven divisions, each representing a different Earth conflict.

Zones in the War Game included the Greek zone, the Roman Zone, the Thirty Years' War zone, the English Civil War zone, the Peninsular War zone, the American Civil War zone, the Mexican Civil War zone, the Crimean Warzone, the Boer War zone, the Russo-Japanese War zone and the 1917 zone, referring to the World War I conflict.

People taken to the War Game included Roman soldiers, a redcoat, Ivan Petrov, Sgt Thompson, Corporal Riley, Leroy, Harper, Arturo Villar, Russell, Lt Jeremy Carstairs, Major Barrington, Sgt Willis, Captain Ransom, Sgt Major Burns, Commandant Gorton, Lt Crane, Du Pont, Lt Lucke, Lady Jennifer Buckingham, Spencer and Moor.

In the war zones created by the War Lords, the Second Doctor and his companions moved from a time zone to another one passing through a mist. The intervention of the Time Lords sent the human prisoners back to their original time zones. (TV: The War Games)
