The Brexit Party has unveiled its policies ahead of the 2019 General Election.
They are pledging to withdraw the UK from the European Defence Union, also known as the Common Security and Defence Policy.
The party formally launched its 'contract with the people' in London on Friday.
Leader Nigel Farage says the party is not calling its policy document a 'manifesto', due to negative associations with the word.
Among its policies, the Brexit Party says it will seek a "clean-break Brexit", "free from entanglement in the EU's integrated defence... policies".
The party's other military-related promises include maintaining the UK's NATO commitment to keep defence spending at 2% of GDP.
They also pledge to raise £200 billion through policies such as scrapping HS2 and redirecting a portion of the foreign aid budget, and to invest in digital infrastructure.
When asked about the lack of detail about defence and veterans in their policy document, Mr Farage said it was a "deliberate" decision to wait until the upcoming NATO summit on 2 December.
He did, however, discuss he views on the future of Five Eyes, an intelligence alliance including the UK, US, Australia, Canada and New Zealand, and European defence.
"The withdrawal agreement does not take us out of the European Defence Union," he said in London.
"I do want to have a debate about the European army during this General Election, I do want to have a debate about this Five Eyes network.
"I honestly think we face a choice now - do we stick with Five Eyes, do we stick with NATO, or do we see the emerging European Defence and Security union as the way forward?
"I don't think we can go doing both.
"I hope that it’s a subject that the public start to think about."
