Roman Contubernium Tent: A tent was 3 by 3.5 metres (0.6 m for the aisle), ten men per tent. Ideally a company took 10 tents, arranged in a line of 10 companies, with the 10th near the Porta Decumana. Of the c. 9.2 square metres of bunk space each man received 0.9, or about 0.6 by 1.5 m, which was only practical if they slept with heads to the aisle. The single tent with its men was called contubernium, also used for "squad". A squad during some periods was 8 men or fewer.
