The only ribbons or medals that a recruit can get while in boot camp is the National Defense Service Medal and the Pistol Marksmanship Medal. When you earn "Expert" you get both a medal and a ribbon. For general marksmanship and "Sharpshooter" you only earn a ribbon.
The National Defense Service Medal is what sailors call a "geedunk" medal since you don't earn it, it is just given to you because you served honorably during a designated time period of which a "national emergency" had been declared. Everyone gets it.
The other one they you can earn while in boot camp is the Pistol Marksmanship Ribbon. There are 3 levels:
Marksman:
Sharpshooter:
Expert:
