Thats the US way of pronouncing the word carbine. Also the word ration as in ration pack, we say 'rashion' while the US say 'rayshun' Same as saddist, they say 'saidist', we say 'sadist'.
There is tonnes of words said diferently between them and us. For the word semi, as in semi automatic, we say 'semee', they say 'semeye'.
Cheers,
