What two groups make up Jackson and army in the battle of New Orleans?

In the Battle of New Orleans, General Andrew Jackson commanded a diverse coalition of forces that included regular U.S. Army soldiers and local militia units. Additionally, his army was bolstered by volunteer fighters from various backgrounds, including free African Americans, Native Americans, and pirates, notably Jean Lafitte and his Baratarians. This eclectic mix of troops played a crucial role in the decisive American victory against the British in January 1815.
