The 20th Infantry Regiment ("Sykes' Regulars")^[1] is a United States Army infantry regiment. Currently only the 5th Battalion of the 20th Infantry still exists. Stationed at Joint Base Lewis-McChord and part of the 1st Stryker Brigade Combat Team, 2nd Infantry Division, 5-20 Infantry was one of the original battalions selected to take part in the testing and fielding of the U.S. Army's then-new Stryker vehicle. During the Vietnam War, elements of the regiment carried out the My Lai massacre.
