According to the Department of Defense's budget materials on their website, the combined military recruitment and advertising budget is $1,407,100,000 ($1.4 billion). Here is a break down by branch of the military:
MARINE CORPS $123,465,000
AIR FORCE $132,349,000
As with all things though it depends on how you define things. This is only looking at the specific line item for "Recruiting and Advertising" which falls under a larger category of "Recruiting and Other Training and Education". If you add up this larger category (which also includes CIVILIAN EDUCATION AND TRAINING, EXAMINING, JUNIOR ROTC, NATIONAL DEFENSE UNIVERSITY, and OFF-DUTY AND VOLUNTARY EDUCATION), the total is $2.8 billion.
These are the 2006 numbers from the FY 2007 budget, which is the most up-to-date info.
