The DAV Veterans Pulse Survey of 2015, the largest multi-generational survey of US veterans (n = 1,701, nationally representative of approximately 22 million veterans from WWII through post-9/11 eras), found that 79% would, if they had to do it over, repeat their military service. The implied action-side rate of approximately 21% (those who would not or are uncertain whether they would repeat) is the primary metric for this entry. Pew Research’s 2011 survey of 1,853 veterans, including 712 post-9/11 veterans, found that 96% were proud of their service, 93% said it helped them mature, 90% said it taught them to work with others, and 82% said they would advise a young person close to them to join. The two surveys converge on a picture of low to moderate action regret, with pride nearly universal and the “would serve again” rate consistently above 75%.
The inaction side has no direct survey data. No national survey was identified that asks non-veteran civilians whether they regret not serving in the military, and this gap in the literature is notable. The 25% inaction-regret estimate in this entry is theory-derived: it applies the Gilovich-Medvec principle that foregone career and life-path decisions with bounded windows of opportunity generate persistent inaction regret, calibrated conservatively against the career domain’s 22.3% share of top lifetime regrets in Roese and Summerville’s 2005 meta-analysis. Military service is a time-constrained choice (age and physical fitness limits) in the career and identity domains, exactly the categories Roese and Summerville identify as most regret-generative. The 25% is a theoretical prior, not an empirical measurement. It is set modestly above the action-side 21% to preserve the inaction-dominance prediction without overstating a rate that has not been measured.
The resulting 4-point gap is the weakest in this entry set and both rates carry substantial uncertainty. The action side benefits from two large nationally representative samples with near-direct “would serve again” questions, but survivorship bias is significant: veterans who developed severe PTSD or service-related disabilities are under-represented in voluntary panels, and active-duty satisfaction has declined sharply since 2019 (Blue Star Families found only 32% of active-duty families would recommend service in 2023, down from 55% in 2016), suggesting the 21% action regret may understate more recent cohorts. This entry documents the state of the evidence rather than a resolved bilateral comparison: strong action-side data, no inaction-side survey, and a direction of effect that is theoretically predicted but empirically unconfirmed.

[1]DAV (Disabled American Veterans) Veterans Pulse Survey via PR Newswire — Landmark Survey Finds Veterans of All Generations Would Repeat their Military Service, But Don't Feel Supported by Government and the American Public
Primary study
79% of veterans across all generations (WWII through post-9/11) said they would, if they had to do it all over again, repeat their military service.
Excerpt
“"Nearly eight in 10 would, if they had to do it all over again, repeat their service. Almost 8 out of 10 veterans say they would repeat their military service, but only half would encourage their sons and one-third would encourage their daughters to serve."

DAV Veterans Pulse Survey, conducted by global research firm GfK using KnowledgePanel. The survey was completed by 1,701 veterans, nationally representative of America's then approximately 22 million veterans, spanning WWII through post-9/11 eras. The 79% "would repeat" figure implies an action regret rate of approximately 21% (the share who would not or are uncertain whether they would repeat their service). The survey asked directly about whether veterans would make the same choice again, making it a near-direct regret measure. Note: "would not repeat" is not identical to "regrets joining" — some who would not repeat may still view the service as valuable but would not recommend it to others, or are uncertain. The 21% is therefore a plausible upper bound on the action regret rate, not a confirmed regret prevalence.
[2]Pew Research Center — Chapter 2: Attitudes of Post-9/11 Veterans — War and Sacrifice in the Post-9/11 Era
Primary study
96% of post-9/11 veterans say they are proud of their service; 74% say their military experience helped them get ahead in life; 82% would advise a young person close to them to join the military.
Excerpt
“"Veterans who served on active duty in the post-9/11 era are proud of their service (96%), and most (74%) say their military experience has helped them get ahead in life. The vast majority say their time in the military has helped them mature (93%), taught them how to work with others (90%) and helped to build self-confidence (90%)."

Calculation
Pew Research Center "War and Sacrifice in the Post-9/11 Era" survey of 1,853 veterans (including 712 who served after 9/11). The 96% pride rate is not a regret rate; it measures emotional response to service, not whether veterans would make the same choice again. Used here as corroborating evidence that the action-regret rate is low: near-universal pride combined with 79% "would repeat" (DAV) and 82% who would advise a young person to join establish a consistent picture of low service regret among US veterans. The 4% who are not proud provides a directional lower bound on regret.

[1]RAND Corporation — What Americans Think About Veterans and Military Service: Findings from a Nationally Representative Survey
Reference source
54% of Americans would discourage a young person from enlisting as an enlisted service member, but 61% would encourage service via ROTC or a service academy. The split suggests the path to service matters more than service itself.
Excerpt
“"A majority (54.4 percent) would discourage a young person close to them from enlisting in the military. A majority (61.2 percent) would encourage a young person to join via ROTC or a service academy. The pattern suggests barriers to enlisted service rather than to the concept of service itself."

Calculation
RAND RRA1363-7, nationally representative survey. The 54% discouragement rate among Americans in 2023 is used here as context on public perception of enlisted service. This is not a regret rate for non-veterans specifically; it measures what adults would advise a young person, not whether they themselves regret not serving. No published survey directly asks non-veterans "do you regret not joining the military?" The 25% inaction-regret estimate is a theory-derived proxy: it applies the Gilovich-Medvec principle that foregone career/life-path opportunities generate persistent inaction regret, calibrated against the career domain's 22.3% share of top lifetime regrets (Roese and Summerville 2005), with upward adjustment for the time-bounded nature of the military opportunity (age limits, physical fitness windows). The resulting 25% is deliberately conservative — slightly above the action-side 21% to reflect the prediction that inaction regret dominates, without overstating a rate for which no direct measurement exists. The inaction side of this entry is entirely unanchored to a direct survey; the estimate should be treated as a theoretical prior rather than an empirical finding.

Career accounts for 22.3% of top lifetime regrets in a meta-analysis of 11 regret-ranking datasets; people most regret decisions in domains where they see the largest missed opportunities for change and growth.

Calculation
Roese and Summerville (2005) meta-analysis of 11 regret-ranking studies. Career ranks second among lifetime regret domains (22.3%), after education (32.2%). Military service, as a major formative career and identity choice, falls within the career domain. The Gilovich-Medvec prediction is that foregone opportunities (inaction regrets) persist over time as the path not taken becomes idealized while the reasons for inaction fade. Non-veterans who considered service and did not join are in precisely the category Roese and Summerville identify as generating the most durable regret: a significant missed life opportunity in the career and identity domains.
Caveats
THE INACTION SIDE HAS NO DIRECT SURVEY. The action-side 21% is derived as the complement of the DAV Veterans Pulse Survey 2015 "would repeat service" figure (79% would repeat, implying ~21% would not or are uncertain). "Would not repeat" is not identical to "regrets joining" — it includes those who are uncertain or who view the choice as context- dependent. The Pew 2011 finding that 96% of post-9/11 veterans are proud of their service converges with the DAV figure to establish a low-to- moderate action regret profile. Both surveys are subject to survivorship bias: veterans who developed severe PTSD or declined participation are under-represented in voluntary panels. Active-duty satisfaction has been declining since 2019 (Blue Star Families MFLS: 55% recommend service in 2016 vs. 32% in 2023), so the 21% action regret may underestimate regret in more recent cohorts. The inaction-side 25% is entirely theory-derived — no national survey was found that directly asks non-veterans whether they regret not serving. The 25% applies the Gilovich-Medvec temporal principle (inaction regret dominates for foregone life-path opportunities with bounded windows) and the Roese-Summerville career domain estimate, calibrated conservatively to produce a modest gap above the action rate. The resulting 4-point delta is the weakest gap in this entry set and should be treated as directional only. This entry cannot be considered a bilateral regret pair in the usual sense: only one side is measured; the other is inferred from theory. The cultural context of military service varies enormously: the analysis applies to the US voluntary military, not to conscript armies or wartime service where the choice set is not voluntary.
