Good for them.
The HMMWV was never meant to be a direct action platform. It was designed to be a utility vehicle until they started putting TOWs and other heavy weaponry on them. They are a terrible patrol vehicle. Let's hope they can find one quick.
Adding: I'm not sure wether it's such a good idea to put so many soldiers/marines (17 !) in the same combat vehicle. Some of the South African vehicles have been developed to deal with land mines (tire and suspension absorbing the damage), but IEDs made out of four or five artillery shells have been shredding Bradleys, LAVs/Strykers and even an Abrams or two. The V-shaped hull will help, but the IEDs keep getting bigger.
