My understanding is that the US Navy came first

[The Blue Flower]

Why didn't we have a parade and celebration of the Navy? This includes the Marine Corps who initially served on ships--hence 'marine'.

1. trump thought those big manly submarines...

going down the street would make his own manhood look weak in comparison.

2. No, the Navy's birthday is October 13. The Marines November 10.

3. Because October 13 isn't Trump's birthday

Nobody really believes this was celebrating the founding of the US Army.

4. The U.S. Merchant Marine

June 12, 1775 iirc, the date a privateer engaged a British ship. The merchant marines are taken for granted until they're needed.

10. Could do the USAF's ...

78th anniversary.

Seems silly, though--that's not usually a biggie.

Then again, it would be little more than a really large air show, unless they decided to do dogfights, strafe the crowd, fire Tomahawks into buildings and drop bombs on DC, then it would be really and truly, massively unpleasant.

But for the rest, it would mean the equivalent of having a fish show with all the fish out of water and being pulled around on little carts.

Not even sure you could build a holder for a sub or a large ship that wouldn't, just from being hauled over DC potholes, transmit stresses and shocks that would damage the things.

8. No, the Army is the oldest

Drom Google's AI:

The U.S. military branches were founded at different times throughout history. The Army was first established on June 14, 1775, as the Continental Army. The Navy's roots trace back to October 13, 1775, when the Continental Navy was created. The Marine Corps was founded on November 10, 1775. The Coast Guard's history began on August 4, 1790. The Air Force was established on September 18, 1947, and the Space Force on December 20, 2019

9. Old inter-service rivalry joke:

If you tell the Army "Secure that building!" They will surround it with armor and heavy infantry and not let anyone out of it until told to

If you tell the Marines "Secure that building!" They will storm the building, eliminate any resistance, and allow no one to enter it until told to.

If you tell the Navy "Secure that building!" They will turn out the lights, close and lock all doors and windows and post a fire watch

If you tell the Air Force "Secure that building!" They will take out a 30 year lease with an option to buy.

(Please laugh, it's good for you!)
