Jubilant residents of eastern Congo are pouring into their dusty streets this week.

That's a bit of a surprise for Congolese soldiers, better known for corruption, looting and rape than professionalism.
Photographer Peter Muller, who works frequently for the New York Times, says he's seeing a new discipline in the Congolese armed forces.
Muller marched with Congelese soldiers as they launched their final assault on the M23 rebels in a town called Bunagana.
