The named Guard lineage carried to the present unit: the county's battalion is the 2nd Battalion, 151st Infantry, at South Bend — the 293rd of the checklist test is Fort Wayne's

No Guard lineage runs through Osceola itself — no company was ever seated here — so the lineage this ground shares is the county seat's, carried whole at boundary size: the Indiana Army National Guard battalion headquartered in St. Joseph County today is the 2nd Battalion, 151st Infantry Regiment, headquarters and headquarters company at South Bend, an element of the 76th Brigade — the "Nighthawk Brigade," redesignated the 76th Mobile Brigade Combat Team on 16 October 2025, under the 38th Infantry Division. The regiment's lineage, on the Army's lineage record as published by the Military Department of Indiana, begins 24 June 1846, organized from existing companies as the 2nd Regiment, Indiana Volunteers, of the Indiana Brigade, for the Mexican War; the 151st carries 24 campaign credits from the Civil War forward through its predecessor regiments, the 151st Infantry designation in the twentieth century's reorganizations, and the modern two-battalion regiment (organized in its present form from 1977): 1st Battalion at Columbus and 2nd Battalion at South Bend (1963–67; 1977–present), its companies today at Gary/Chicago Airport (A), Logansport (B), Warsaw (C, with a detachment at Peru) and Frankfort (D, Weapons), with Detachment 4, Headquarters and Headquarters Battery, 1st Battalion, 163rd Field Artillery, also at South Bend in the battalion's support. The regimental motto is "Wide Awake! Wide Awake!" Elements of the regiment have deployed to Bosnia, Iraq and Afghanistan. The checklist's test name belongs to the neighbouring city and prints as a boundary correction, not a claim: the 1st Battalion, 293rd Infantry is headquartered at Fort Wayne, and its combat record (the first Guard battalion to earn the Combat Infantryman Badge since the Second World War, in Iraq in 2003) is Fort Wayne's whole. Osceola's share of either lineage is the share Wars & Military Service documents — the township's individual soldiers, marching in county companies — and no Penn company name enters the Guard line at any point in the succession.
