perushuoltoa

Perushuolto, in Finnish military terminology, designates the rear logistical sustainment activities that support military operations by delivering essential services from behind the front lines. It covers planning, provisioning, maintenance, and transport to keep forces supplied and ready. In practice, perushuolto ensures that front-line units have the materials and support needed to operate without interruption.

Key components include depot-based maintenance and repair of vehicles and weapons, supply of spare parts, fuel, ammunition, rations, and clothing, as well as the management of transport and distribution from logistics hubs to forward units. Field workshops and repair teams may operate at rear echelons to perform repairs that cannot be completed in the field, while medical support and casualty evacuation coordination also form part of the broader sustainment function.

Perushuolto is typically organized within the logistics chain of the armed forces, distinct from forward or field maintenance, and relies on established supply lines, depots, and transport assets. It works in concert with front-line maintenance to enable timely replenishment and recovery of equipment, often adapting to operational tempo and risk in the rear areas.

In modern defense practice, perushuolto emphasizes modular, scalable logistics that can be rapidly adjusted to support different missions, environments, and levels of attrition, ensuring operational continuity even under constraints.
