The OSCE provides continued assistance to Montenegrin authorities to dispose of toxic substances, destroy heavy weapons, arms, and unstable, obsolete conventional ammunition. The OSCE Mission to Montenegro is actively working on these tasks supporting the Ministry of Defence. The Mission also helps to upgrade the infrastructure of military storage depots by raising funds for modernization through donor conferences. Mission also works with the Interior Ministry to promote efforts for the reduction and control of small arms and light weapons in possession of the public. 

On 25 June 2019, Montenegro presented an official assistance request to the OSCE Forum for Security Co-operation which was officially announced at the FSC meeting on 9 October 2019 (FSC.DEL/212/19) (Ministry of Defence of Montenegro, 2019). The assistance requested support of OSCE in the following areas:

• reconstruction of the storage site "Brezovik" near Nikšić and reconstruction of the ammunition storage site "Nova lokacija" Židovići – Pljevlja;
• adaptation and equipping the facility designated for maintenance of ammunition (including its disassembling) – in the storage site "Brezovik";
• provision of a stationary surveillance laboratory;
• support and advise in transfer of international experiences and OSCE best practices in selected areas of Life Cycle Management (LCM) of WEO through multi-stakeholder engagement, policy guidance, exchanges and training;
