The site includes this numbered placeholder, but a matching infantry-regiment lineage has not been established. Related training institutes and similarly numbered brigades are identified separately.
The site contains this numbered placeholder, but a matching U.S. infantry-regiment lineage for 1916–2026 has not been established from the reviewed records. A similarly numbered brigade, a Civil War state regiment or a training institute is not assumed to be the same unit.
Division names appear in the timeline. No verified patch artwork is included for these assignments.
Representative division patches. Patterns could change over time; an image does not imply that the exact version was worn throughout every period. Divisions without a verified asset remain identified by name.
At a glance
Bar widths follow elapsed time.
Scroll horizontally on a small screen. Select a segment to open its dated entry. Diamond markers open deployments; their positions indicate the labeled year, not an exact start date or duration. Short assignments are easier to inspect in the list below.
Explore a date
Look up the dated rows below. Service notes with incomplete dates are excluded; last-documented results do not certify a current assignment.
The dated record
No deployment with sufficiently established dates is plotted for this regiment. Read the assignment cards and service notes for its garrison, training and successor-unit history.
Assignment ends are exclusive: the next period starts on that date. *Striped final bars mean last documented, with later status unverified through the page cutoff. Unknown intervals are not treated as inactive.
192d Infantry · Regimental numbering record
The available record does not establish a precise assignment throughout this interval. No division is inferred. The source establishes this last recorded status, not uninterrupted service through 2026. The striped bar extends to the page cutoff to keep the later research gap visible.
Service note · dates incomplete
A brigade with this number must not be used to populate the division history of an infantry regiment. No regimental battalions or deployments are inferred from the site’s existing graphics.
Army Center of Military History lineage certificates, regimental associations and secondary histories document assignments, operations and battalions. Exact lineage dates and approximate historical coverage are distinguished. Where the evidence stops, the page says so. A page cutoff is not a claim that every unit directory was current on that date.
Earlier battalions are covered by common regimental service; separately dated lineages and substantiated later battalions receive their own rows or notes. A unit graphic alone is not evidence of a battalion assignment. Reserve, training and inactive organizations are distinguished from active combat units.
