This is a charade - multiple word parts are joined together in sequence to form the answer.
Take 'Roger' (a name in the NATO phonetic alphabet) and reverse it ('backing'), then add it to a word meaning 'strike'. Put these parts together in order.
Answer: KOPECK | 'Roger' in NATO phonetic alphabet is KILO, reversed ('backing') gives OLIK, but we want just KO. 'Strike' = PECK. KO + PECK = KOPECK (Russian monetary unit).
