what does the red stripe on the marine uniform mean
Blood stripe Tradition holds that in the Battle of Chapultepec in Mexico on September 1847, Marine officers and NCOs sustained an unusually high casualty rate during the battle.[4][clarification needed] In 1849, uniform regulations dictated that the stripes be changed to a solid red in honor of the numerous Marine deaths. Ten years later, a scarlet cord was inserted into the outer seams for noncommissioned officers and musicians, while a scarlet welt was added for officers. Finally, in 1904, the simple scarlet stripe seen today was adopted, with the varying widths prescribed for different ranks.
Trooping the Colour Trooping the Colour is an old ceremony whereby a battalion would fall in by companies and the colour-party would "troop" or march the colours through the ranks so that every man would see that the colours were intact. This was done before and after every battle. This ceremony has been retained through time and is today largely ceremonial.
