UKIP believes the UK is "unneccessarily at loggerheads" with Russia following the Ukraine crisis, according to the party's manifesto.
The document, which was unveiled on Wednesday, criticises the Ministry of Defence for offering Ukraine "any possible assistance" to fight off the Russian threat after the annexation of Crimea.
The MoD has given Ukraine "non-lethal equipment" such as combat helmets and first aid kits, and has also provided training to Ukrainian troops.
UKIP leader Nigel Farage has previously said that he admires Vladimir Putin, and UKIP MEP Diane James last week praised Putin for "standing up for his country".
The passage in the manifesto, signed off by Farage, says conflict with Russia is unnecessary:
Britain's increasing involvement with European Union expansionism is putting us, increasingly, unnecessarily, at loggerheads with Russia. The MoD recently told Ukraine it can count on 'any possible assistance' in maintaining its territorial integrity. It is yet another sign that our political leaders are willing to put our troops in harm's way at the behest of other country's political agendas.
It goes on to say British troops shouldn't be sent to conflicts "at the drop of a hat".
We have to be clear: we should stand firmly alongside our allies around the world, but cannot continue committing troops into conflict at the drop of a hat – often under-resourced – and with a veterans policy that lets down those returning from the horrors of war.
