In preparation for their bowl game on Saturday, Navy used their strategic training to pull off a major prank on ASU.
Navy fans snuck up to "A" Mountain, painted the "A" navy and gold and wrote "Go Navy."
Sun Devil fans didn't do a very good job protecting their "A."
Hopefully the Sun Devils can put up a better defense against Navy during the Kraft Fight Hunger Bowl in San Francisco on Saturday.
FOX 10's (and ASU alum) Kristin Keogh reports from the base of "A" Mountain.
