In time-phased force and deployment data (TPFDD) development, what term refers to the unit line numbers used by planners at the support component headquarters?

• A. Unit line numbers (ULN)
• B. Unit indicator codes (UIC)
• C. Unit manning documents (UMD)
• D. Unit type codes (UTC)

Answer: (A)

In TPFDD development, the unit line numbers are the identifiers that planners at the support component headquarters use to reference each unit’s deployment line within the schedule. These numbers uniquely map to a unit’s entry in the time-phased data, letting planners track when that unit is expected to deploy, move, and be sustained, and how it fits into the overall timeline and transport plan. This makes coordination across movement, logistics, and timelines precise and auditable. Unit line numbers differ from other terms: a unit identification code (UIC) identifies the unit in records and databases, a unit Manning Document (UMD) lists authorized and actual personnel, and a Unit Type Code (UTC) describes a standard mission capability. The ULN specifically designates the line item for planning and execution within the TPFDD.
