National support element

The National Support Element (NSE) is a military unit established to provide logistical and administrative support to deployed national contingents within multinational operations. Originating in the late 20th century with the increasing prevalence of coalition missions, NSEs are typically responsible for supply, transportation, personnel administration, and coordination with both host nation and allied support structures. The concept gained prominence during operations such as the NATO missions in the Balkans and Afghanistan, where seamless national support was vital for operational effectiveness. Today, NSEs remain a critical component in ensuring the self-sufficiency and readiness of national forces operating abroad.
