That's right - this is the new face of the U.S. Marines ... and what a cute face it is. The name of this adorable nine-week-old English bulldog pup is "Chesty," and he'll now be known as Private First Class "Chesty," replacing the current mascot ... who's a sergeant!

Chesty's duties will be many, and will include marching in parades and other public appearances. Best of luck, Chesty!
