Clash of Clan | COC Barracks How it Work

Clash of Clan Barracks allow players to unlock troops and reduce training time.
Upgrading one Barrack will unlock a new troop.
Upgrading additional Barracks to the same level will reduce the training time of that troop.
The more Barracks at that level, the faster that troop will train!

Barracks on upgrading, they’re unable to train troops and time training reductions from that Barrack until the upgrade is complete. If all Barracks supporting one troop type are under construction, that troop cannot be trained!

In short:
* Barracks upgrades will unlock a new troop or reduce a troop's training time
* Troops will train slower (and might become unavailable) when Barracks are under construction
