When were the Continental Army, Navy, and Marines established?

The Continental Army, Navy, and Marines were all established in 1775, which is why this option is the correct answer. The establishment of the Continental Army was a direct response to the escalating conflicts with Great Britain, particularly in the wake of the Battles of Lexington and Concord in April 1775. This built a unified military force to combat British troops and assert American independence.

The Continental Navy was also created in 1775 to support the army by engaging British naval forces and protecting American shipping, while the Continental Marines were established around the same time to serve as a specialized infantry unit trained for shipboard combat and landing operations. This cohesive military development was crucial in laying the foundation for what would later become the U.S. military services we know today.

Establishing these branches in 1775 was a pivotal moment in American history, as it marked the beginning of organized military resistance against British rule.
