2731st

2731st is a numerical designation used by various organizations to identify a specific unit, office, or subdivision within a larger hierarchical structure. In military contexts, designations such as the 2731st are assigned to units like battalions, squadrons, groups, or wings to distinguish them from other units with similar roles. The exact meaning of the numeral depends on the country, service branch, and historical period, and the same number may be reused for different units over time or in different theaters, meaning that bearing the number does not guarantee continuity with another unit of the same numeral.

Beyond the military, ordinal numbers of this form appear in civil administrations, research institutes, and government programs to label departments, offices, or project lines within larger organizations. The designation is typically a label rather than an indication of function, capability, or size, and it often requires accompanying context such as the parent organization and the time period to interpret correctly.

In archival sources and insignia lists, the 2731st may be encountered as a standalone label on documents, equipment, or patches, with full titles providing the complete designation. As with other numerical designations, the usage of 2731st reflects administrative conventions rather than a universal meaning.
