Of course there are other holidays set for today and some overly zealous patriots might wonder why I did not pick National Marine Corps Day and the answer is simple - I always try to pick food related holidays.

and on that note:

Latin for “Always Faithful,” Semper Fidelis is the motto of every Marine—an eternal and collective commitment to the success of our battles, the progress of our Nation, and the steadfast loyalty to the fellow Marines we fight alongside.

The Marines' Hymn Song by United States Marine Band Lyrics:

From the Halls of Montezuma
To the shores of Tripoli;
We fight our country's battles
In the air, on land, and sea;
First to fight for right and freedom
And to keep our honor clean;
We are proud to claim the title
Of United States Marine.
Our flag's unfurled to every breeze
From dawn to setting sun;
We have fought in every clime and place
Where we could take a gun;
In the snow of far-off Northern lands
And in sunny tropic scenes,
You will find us always on the job
The United States Marines.
Here's health to you and to our Corps
Which we are proud to serve;
In many a strife we've fought for life
And never lost our nerve.
If the Army and the Navy
Ever look on Heaven's scenes,
They will find the streets are guarded
By United States Marines.
