Army Camp/Home Village

"Your troops are stationed in Army Camps. Build more camps and upgrade them to muster a powerful army. If an army camp is destroyed, all troops will perish "

Troops will not persish as of 2012 Halloween update.

Summary
The Army camp takes up a 5x5 space. They continue to function even when they are being upgraded, allowing you to keep your armies at full capacity at all times.

In the Halloween update, troops would not die even after one's camps are destroyed. Due to people's support towards keeping this feature, Supercell has made it permanent. Now troops inside the camp, even if destroyed, don't perish.

The Army camp is where your troops go when they're done training. Some troops may take up more than one space (giants, wizards, etc.) Upgrading and building more Army camps allow more troops to be stored, allowing higher chances of victory in raids. The troops inside will NOT defend your village, only ones in the clan castle can.The army camp looks change at each level.

The highest amount of troops you can have is 220 house spaces (4 army camps x 55 space).

Trivia
