An Egyptian man walks past an Egyptian military M113 armored personnel carrier following noon prayers in Cairo on Friday. Egypt has around 2,000 of the BAE Systems-made vehicles, first developed by U.S. firm FMC and later United Defense. The Egyptian military depends on the U.S. for over $1 billion annually in military aid. But, after Egyptian forces reportedly killed hundreds of protesters after ousting the elected president, there are widespread calls to end monetary aid and hardware shipments.
