Its not really a cheat, but on the lvl when u find u have sherman, when u go in the train station there is a bridge that trains go under. if u jump (vault the railings) on top of the train as it goes past, it goes underneath u, if u look down u find ur flying! ( i kill loads of guys from there)
On the second level at the second baracade there is a tank behind it but dont worry the barracade will protect you the tank will shoot you and it will not effect your health.
