Everyone knows the meaning of semper fidelis. But today, the USO takes a look at 29 other Marine Corps facts that may surprise you on the service’s 239th birthday:

  1. Marines often pin their next promotable rank onto their uniforms as a motivator. They usually hide it in their cover or under a pocket flap.

  2. The Marine Corps’ first amphibious raid was only weeks after its creation when Marines successfully stormed a British weapons cache in the Bahamas.

  3. The Marines’ first land battle on foreign soil was in Libya, where 600 Marines stormed the city of Derna to rescue the crew of the USS Philadelphia from pirates.

  4. Male Marine recruits attend boot camp in one of two locations, depending on which side of the Mississippi they’re from: Marine Corps Recruit Depot (MCRD) San Diego for West Coast recruits (which is a separate facility from Camp Pendleton) and MCRD Parris Island for East Coast recruits.

  5. Female recruits only attend MCRD Parris Island.

  6. MCRD San Diego can be seen from the air if you fly into San Diego International Airport, causing recruits to wonder if the airport was built there to torment them.

  1. Because MCRD Parris Island was the first of the two depots, Marines who attend MCRD San Diego are often called “Hollywood Marines” by Parris Island Marines. Hollywood Marines don’t have a name for Parris Island Marines because they feel bad about the sand fleas.

  2. Since then-Secretary of Defense Leon Panetta ordered the military to integrate women into combat arms occupations in January 2013, more than 18 female infantry officer candidates have attempted the qualification course. To this point, all 18 have failed to qualify.

  3. Marines regularly train with their international counterparts from more than 15 different nations. See if you can hear/see the similarities between these Tongan Marines and U.S. Marines.

  4. U.S. Marines also let their hair down at times while training with allied forces. Check out this drum battle with the South Korean Army band.

  1. The Marines have won four out of five Warrior Games competitions. This year marks their first loss to the Army.

  2. Terrance Ford, brother of Harrison Ford, leads a photography program for wounded transitioning Marines at Wounded Warrior Battalion West on Camp Pendleton, called fStop Warrior Project.

  3. Marine recruits are finished eating the moment their drill instructor is finished. This is why Marines eat so fast.

  1. Fewer than 100 people have received the title of honorary Marine, a title that can only be bestowed by the Commandant of the Marine Corps. Here are a few of their names and ranks in order of seniority:
    • Chuck Norris (rank unknown but also unneeded)
    • Brig. Gen. Bob Hope
    • Master Sgt. Bugs Bunny
    • Cpl. Jim Nabors, star of Gomer Pyle, U.S.M.C.
    • Gary Sinise
  2. “Hurry up and wait” is what happens when each leader down the chain of command tells his or her Marines to be there 15 minutes prior to the senior’s directive. This is why Marines arrive early to their destinations.

  3. The license plate of the Commandant of the Marine Corps reads “1775.”

  4. Marines in uniform are not authorized to put their hands in their pockets.

  5. Only female Marines are authorized to carry umbrellas in uniform.

  1. The rank of Marine “gunner” is the only Marine Corps rank that requires different insignia on the left and right uniform collars (*The rank of colonel requires the eagles on each collar to be mirror images of each other, so they are also technically different insignia).

  2. In the Corps, because of the total hours off, a three-day weekend is called a “72” and a four-day weekend is called a “96.”

  1. The Marine Corps mascot is an English bulldog named Chesty, after Marine Lt. Gen. Louis B. “Chesty” Puller, the only Marine to earn five Navy Crosses.

  2. Even though the Corps is an amphibious force, swim qualification is one of the few annual qualifications that doesn’t count toward a Marine’s promotion to the next rank.

  3. A three-volley salute performed at funeral ceremonies is often confused with a 21-gun salute. The three-volley salute is the firing of three rifle volleys (rounds) over the graves of fallen armed forces members and political leaders and can be traced to the European dynastic wars, when fighting was halted to remove the dead and wounded. Once an area was cleared of casualties, three volleys were sent into the air as a signal to resume fighting. Three, five or seven Marines can perform a three-volley salute.

  4. Every year, Thai Marines instruct U.S. Marines in a day of jungle-survival training as part of the annual exercise Cobra Gold. The training culminates with the U.S. Marines participating in a Thai warrior ritual that involves cutting a cobra’s head off and drinking its blood.

  1. According to Marine sniper superstition, there is ultimately one round destined to end the life of a Marine, and that is “the round with your name on it.” Until that round is fired, the person for whom it is intended remains invincible. If the sniper carries the round with him at all times, it can never be fired and the sniper is therefore untouchable. Out of school, a Marine sniper carries the colloquial title “PIG,” or a Professionally Instructed Gunman, until he has killed an enemy sniper in combat and removed the round with his name on it from the enemy sniper’s magazine. That round is then worn as a necklace and symbolizes his new status as a HOG, or “Hunter of Gunmen.”

  2. Ever since Vietnam, Marine amtrac crews will not eat apricots, as they’re considered bad luck.

  3. Marines also think it’s unlucky to eat the CHARMS that used to come in packs of meals ready to eat.

  4. Marines are often called jarheads because of their high-and-tight haircuts, but some Marines take this cut to the extreme. Unauthorized haircuts include the horseshoe and the mohawk.
