The UK has joined a Dutch-led military project that will better allow British troops to deploy across Europe.
The Defence Secretary Ben Wallace said the UK joining the Military Mobility project will also allow for the better deployment of military "equipment across Europe and crucially support EU-NATO cooperation".
"Working with our EU partners, we will ensure greater European security and a collective and determined response to our support for Ukraine," he said.
On 6 October, member states of the Military Mobility voted to support the UK joining, before the EU's Foreign Affairs Council (Defence) approved the UK's application.
Joining the project will allow UK requirements to be considered in EU-decision making on everything from transport infrastructure to cross-border military transport procedures.
NATO sets the framework that governs the movement of forces across the alliance, however the EU is vital in supporting cross-border procedures, allowing easy passage.
The EU also ensures the union's infrastructure takes into account the military requirements of its member states.
The Ministry of Defence said they "support all efforts to structure and cohere cooperation between partners and allies".
They added this included "ensuring multi-national security bodies such as NATO, the EU and the [Joint Expeditionary Force] are working to complement each other".
