The barracks of Division three are similar to the captain's room. They all contain separate rooms with soft beds, each room having one offshoot room for changing and washing. There are several trees outside the barracks and they line the walkways The only reason they are there is because Shu decided they should be.
The outside of the barracks is tidy and clean. The walls have a pure white shine, always clean. Shu, though lazy himself, may or may not randomly order a full barracks cleaning, just to keep the division on their toes. The most common activity outside of training and sleeping, would be harvesting the fruit from the trees, which often make up the division's meals as well. Shu especially stresses this since, as a blitzkrieg force, they should be able to handle themselves in the event other food isn't readily available.
