Barracks - Clash of Clans building breakdown
Barracks are where you 'train' troops - in other words, where you generate them so they can join your happy army on your happy Army Camp(s). Upgrading Barracks unlocks the ability to train new, more powerful troops - essential for ensuring higher-level raids are successful.
Initially, it is sensible to focus on upgrading one Barracks above others in order to gain access to higher-level troop units. However, don't go too crazy as this strategy can cause difficulties in the mid-term. Eventually you will want to evenly upgrade all of your Barracks as this cuts down on the overall training time by making it possible to spread higher-level troops (which require longer to train) across your available Barracks.
Unlike Army Camps, Barracks do not continue their function while being upgraded. So take this into account when planning your strategy.
