The Continental Army was the national army of first the Thirteen Colonies, and then the independent United States, during the American Revolutionary War, established by a resolution of the Congress on June 14, 1775, three days before the Battle of Bunker Hill, where it saw its first action under that title.. The Continental Congress took a number of steps in the spring of 1775 to create the army in response to the Battles of Lexington and Concord in April and the seizure of Fort Ticonderoga in May. The units composing the Continental Army changed frequently, especially in the first two years of the war. From 1777 to the close of the war, the organization of the Continental Army became progressively more systematic and sophisticated. The Continental Army that served at Yorktown in 1781 bore very little resemblance to the Continental Army that blockaded Boston in 1775.

The Continental Army was the army raised by the Second Continental Congress to oppose the British Army during the American Revolutionary War. The army went through three major establishments: the first in 1775, the second in 1776, and the third from 1777 until after the end of the war.

The army went through three major establishments: the first in 1775, the second in 1776, and the third from 1777 until after the end of the war. The 1776 differed in some significant ways from both the 1775 establishment and the 1777 establishment.

The 1st Canadian Regiment, an Extra Continental regiment, was raised by James Livingston to support Colonial efforts in the American Revolutionary War during the invasion of Quebec. Livingston recruited men from Chambly, Quebec as early as September 1775, but a formal regimental designation was made by Richard Montgomery on November 20, 1775, with recognition by the Second Continental Congress following on January 8, 1776. The regiment, which never approached its authorized size of 1,000 men, saw action primarily in the Canadian theater and New York, and was disbanded on January 1, 1781, at King's Ferry, New York.

The 2nd Canadian Regiment, also known as Congress' Own or Hazen's Regiment, was authorized on January 20, 1776, as an Extra Continental regiment and raised in the province of Quebec for service with the Continental Army under the command of Colonel Moses Hazen. All or part of the regiment saw action at Staten Island, Brandywine, Germantown and the Siege of Yorktown. Most of its non-combat time was spent in and around New York City as part of the forces monitoring the British forces occupying that city. The regiment was disbanded on November 15, 1783, at West Point, New York.
The 2nd Continental Artillery Regiment also known as Lamb's Continental Artillery Regiment was authorized on 1 January 1777 as Colonel John Lamb's Continental Artillery Regiment. As originally constituted, the regiment included 12 artillery companies from New York, Connecticut, and Pennsylvania. The bulk of the regiment served in the Hudson Highlands, though some companies fought with George Washington's main army from 1777 to 1779.

The Commander-in-Chief's Guard, commonly known as Washington's Life Guard, was a unit of the Continental Army that protected General George Washington during the American Revolutionary War. Formed in 1776, the Guard was with Washington in all of his battles. It was disbanded in 1783 at the end of the war.

The United States Army Corps of Engineers (USACE) is an engineer formation of the United States Army that has three primary mission areas: engineer regiment, military construction, and civil works. The day-to-day activities of the three mission areas are administered by a lieutenant general known as the commanding general/chief of engineers. The chief of engineers commands the engineer regiment, composed of combat engineer army units, and answers directly to the chief of staff of the army. Combat engineers come from throughout the service and can be active duty, national guard, or army reserve. Combat engineers duties are to construct fighting positions, fixed/floating bridges, and obstacles and defensive positions, place and detonate explosives (sappers), conduct operations that include route clearance of obstacles and rivers, prepare and install firing systems for demolition and explosives, and detect mines. For the military construction mission the commanding general is directed and supervised by the assistant secretary of the army for installations, environment, and energy, whom the President appoints and the Senate confirms. Military construction relates to construction on military bases and worldwide installations.

The Maryland and Virginia Rifle Regiment, most commonly known as Rawlings' Regiment in period documents, was organized in June 1776 as a specialized light infantry unit of riflemen in the Continental Army during the American Revolutionary War. The American rifle units complemented the predominant, musket-equipped, line infantry forces of the war with their long-range marksmanship capability and were typically deployed with the line infantry as forward skirmishers and flanking elements. Scouting, escort, and outpost duties were also routine. The rifle units' battle formation was not nearly as structured as that of the line infantry units, which employed short-range massed firing in ordered linear formations. The riflemen could therefore respond with more adaptability to changing battle conditions.

The Virginia Line was a formation within the Continental Army. The term "Virginia Line" referred to the quota of numbered infantry regiments assigned to Virginia at various times by the Continental Congress. These, together with similar contingents from the other twelve states, formed the Continental Line. The concept was particularly important in relation to the promotion of commissioned officers. Officers of the Continental Army below the rank of brigadier general were ordinarily ineligible for promotion except in the line of their own state.
