Allah akbar is a pronouncement meaning that religious followers believe that Allah is a greater, more powerful God than any other god.
In battle, if an opponent is killed, the survivor might say, "Allah akbar" as an acknowledgement that his survival is obvious proof of his belief that Allah is indeed greater than the god of his dead opponent. After all, he lived and the other guy didn't.
