Naval dockyard in the context of "Rear (military)"

In military parlance, the rear is the part of concentration of military forces that is furthest from the enemy (compare its antonym, the front). The rear typically contains all logistic and management elements of the force necessary to support the front line forces, and generally constitutes supply depots, ammunition dumps, field hospitals, machine shops, planning/communication facilities, command headquarters, and infrastructure such as roads, bridges, airfields, dockyards, and railway depots.

Military personnel in the rear are usually called the rear detachment, and they are responsible for staffing, supplying, and maintaining the rear elements. The rear is considered a crucial part of military organization, and it can sometimes outnumber the unit's front line force by several times.
