3rd Infantry Regiment Battalions
Modern Era, United States, Infantry
This second-pass battalion page ties the 3rd Infantry Regiment icon set more directly to the parent regiment's history. The local icon set presents the 1st, 2d, and 3d Battalions, while the better-documented modern Old Guard story emphasizes the 1st, 2d, and 4th Battalions.
1st Battalion, 3rd Infantry Regiment
The 1st Battalion best captures the Old Guard's most visible modern identity. After the regiment's 1948 return to the Washington area, the 1st Battalion became one of the principal carriers of the regiment's ceremonial and security mission while preserving the Army's oldest active infantry lineage.
That makes the 1st Battalion the clearest battalion-level expression of the regiment's postwar role: funeral honors at Arlington, presidential ceremonies, and the public face of a regiment whose history runs back to 1784.
2d Battalion, 3rd Infantry Regiment
The 2d Battalion represents the Old Guard's operational side. Vietnam brought the regiment back into field service through separate battalions, and the 2d Battalion became the best-documented modern maneuver battalion of the regiment when it deployed with the 199th Light Infantry Brigade in 1966.
That field identity carried forward after Vietnam. In the post-Cold War era, regiment elements again deployed operationally, and the 2d Battalion remained the easiest battalion through which to understand how the Old Guard balanced ceremonial prestige with real combat service.
3d Battalion, 3rd Infantry Regiment
The local icon set includes a 3d Battalion, but the regiment's better-documented modern battalion story points instead to the 4th Battalion alongside the 1st and 2d. For that reason this section remains a heritage placeholder inside the icon set rather than a firm battalion lineage narrative.
Any later battalion-specific research pass for the 3rd Infantry should revisit this slot together with the Vietnam-era 4th Battalion, since that is where the parent regiment page places the clearer battalion history.
Research note: This second pass replaces the earlier short sketch with stronger regiment-specific context. The 3d Battalion entry remains intentionally cautious because the local icon set and the regiment's better-documented modern battalion story do not align cleanly.
