Executive summary

Pete Hegseth’s public biographies and reporting indicate National Guard service spanning roughly 2003–2021 with later reserve/IRR status and a final Guard stint in 2019–2021; several sources state he held the rank of major at or after his 2015 promotion [1] [2] [3]. Available sources do not give a single undisputed—day‑by‑day—length of continuous service but describe multiple separate periods of service that together cover roughly 2003 through 2021 with additional IRR/administrative separation later [1] [2].

1. The basic timeline reporters and official bios use

Multiple accounts trace Hegseth’s commissioning to 2003 after Princeton ROTC and list deployments to Guantánamo Bay, Iraq and Afghanistan over several tours; those sources say he served in the National Guard in distinct phases from the early 2000s through 2021 [1] [2] [3]. TogetherWeServed’s profile and Ballotpedia both summarize service windows and deployments covering 2003–2006, a later active return in 2012–2014, and a rejoining in 2019 that lasted into 2021 [1] [2].

2. How long did he serve — aggregated, not continuous

Reporting aggregates Hegseth’s service as spanning roughly 2003 to 2021, with intermittent active-duty and reserve/IRR assignments rather than an unbroken active-duty career [1] [2]. Some outlets describe this as “served from 2003–2021” while noting promotions and IRR status that complicate a simple continuous‑service count [1] [2].

3. Rank at separation — what the sources state

Multiple sources say Hegseth was promoted to major by about 2015 and thereafter served in the Individual Ready Reserve (IRR); those same sources report he held the rank of major while in IRR and during later National Guard affiliation [1] [2] [3]. Encyclopedic summaries (Britannica, Ballotpedia) list “major” as his terminal rank in public records [3] [2].

4. Where the records are granular — deployments and promotions

Details cited across profiles: initial commissioning as an infantry officer after Princeton ROTC in 2003, an 11‑month Guantánamo tour, deployments to Iraq where he served as an infantry platoon leader and civil‑military officer, a 2012 return to active duty as a captain, promotion to major after 2014 and assignment to the IRR in 2015, and a reentry to drilling status in the D.C. Army National Guard from mid‑2019 until about March 2021 [1] [2] [3].

5. Ambiguities and limits in public reporting

Sources use slightly different phrasing—some say “served from 2003–2021,” others list discrete tours and IRR intervals—so a precise continuous service duration (total active duty days versus reserve/IRR days) is not spelled out in these reports [1] [2]. Available sources do not provide an exact administrative separation date tied to a personnel action that would let us state a definitive “length of continuous service” in calendar years beyond the aggregated span noted above [1] [2].

6. Why different outlets vary in wording

Encyclopedic and official biographies compress a multi‑phase Guard career into a span; veteran‑oriented sites and local profiles provide more phase detail (active duty, IRR, later drilling status). That produces statements that either present a continuous‑looking 2003–2021 span or a segmented career with promotions and reserve assignment—both are accurate descriptions of the same underlying record but emphasize different elements [1] [2] [3].

7. Takeaway for readers evaluating claims

If you see headlines saying Hegseth “served from 2003–2021” and “separated as a major,” those statements reflect the consensus in available profiles and biographies [1] [3] [2]. If you need an exact total of active‑duty days, IRR time, or the precise administrative separation date, available sources do not provide that level of personnel detail [1] [2].

Limitations: this summary relies only on the provided profiles and reporting; official personnel files or a DoD separation memo would be the authoritative way to confirm exact service‑length accounting and final separation paperwork, but such documents are not in the supplied sources [1] [2].
