Founded in 1975, four-time professional league champions, Enisey-STM, are based in Krasnoiarsk in the heart of Siberia.
Their name stems from the Enisey river, one of the largest in Russia, and STM is an abbreviation of the Siberian Heavy Engineering Plant earning the team the nickname, 'Heavy Machine'
This will be the third year running that the Connacht 'A' team has faced the Russian opposition with Connacht taking the spoils last April and this year sees Connacht name one of the strongest 'A' sides yet.
