The U.S. military faces a serious recruitment problem, one that is becoming more critical as global conflicts intensify. Although much of the media coverage surrounding the wars in Ukraine and Gaza focuses on high-tech weapons, the real issue still boils down to having enough troops. Despite the technological advancements and reliance on machinery, people are the most important resource in modern warfare.
Take Ukraine, for example. By the fall of 2023, an estimated 200,000 battlefield deaths occurred between Ukrainian and Russian forces. Though advanced U.S. weapons aided Ukraine, it was ultimately the citizen-soldiers and local militias that staved off total Russian conquest in 2022. Russia, too, stabilized its lines by mobilizing over 300,000 troops, preventing collapse in the latter part of that year. Both sides now face the challenge of keeping new recruits flowing into their military ranks, going so far as to include older men, women, and even convicts in their numbers.
The same pattern is visible in the Middle East. On October 7, 2023, Hamas fighters, equipped with basic, low-tech tools, breached Israel’s automated defense systems surrounding Gaza. Despite Israel’s reputation as a technological leader, the breach was repelled by ordinary conscript soldiers and volunteers. Israel’s swift call-up of 360,000 reservists helped them launch a successful counterattack against Hamas and deter threats from Lebanon and the West Bank.
While other countries rush to mobilize reserves in wartime, the U.S. eliminated its draft 51 years ago, instead relying on an All-Volunteer Force (AVF). But the truth is, this system isn’t purely volunteer-based—it’s a heavily recruited force. In the past, the U.S. military would enlist roughly 150,000 young Americans annually, mostly through targeted efforts and incentives. While this worked during the Iraq and Afghanistan wars, the AVF now faces a far more challenging environment, where not enough young people are willing or able to join.
In 2023, three of the four major U.S. military branches failed to meet their recruiting targets. The Army, for instance, missed its goal by 10,000 soldiers, a 20% shortfall. The active-duty Army, which now has 445,000 troops, is the smallest it’s been since 1940. Other branches like the Navy and Air Force also fell short. The only branch to meet its goal was the Marine Corps, but that success is partly due to force cuts under its Force Design 2030 plan, which left them with fewer slots to fill.
The problem extends beyond active duty. Reserve components like the National Guard and Reserves are facing even worse recruiting challenges. For instance, the Air National Guard and Air Force Reserve missed their recruiting targets by 30% last year, while the Army Reserve fell short by a similar margin.
In the event of a major war or national emergency, the U.S. would struggle to mobilize forces quickly. The Individual Ready Reserve (IRR), designed to activate former military personnel during times of crisis, has shrunk to just over 264,000 members. The Army’s IRR pool alone dropped from 700,000 in 1973 to a mere 76,000 in 2023. This means the military would have difficulty even replacing casualties from the initial battles of a high-intensity conflict.
One of the most alarming aspects of the recruitment crisis is that fewer young Americans are eligible to serve. Before the COVID-19 pandemic, only about 30% of Americans aged 17 to 24 were eligible. That number has since dropped to 23%. Reasons for disqualification include obesity, poor physical fitness, mental health issues, and drug use. Even scores on the military’s standardized exam, the ASVAB, have declined, leaving fewer qualified candidates.
The new military health system, MHS Genesis, introduced in 2022, has made recruitment even more difficult. This system reviews civilian health records and flags disqualifying factors like old sports injuries or mental health counseling. While this has improved the enforcement of the military’s medical standards, it has made it harder for recruiters to meet their quotas.
Even among those who are qualified, fewer young Americans are interested in joining the military. A 2022 Pentagon poll found that less than 10% of people aged 16 to 21 would consider enlisting. Those who do show interest are often motivated by financial benefits like pay, college tuition, or career skills, rather than a sense of duty or honor.
Nearly 80% of recent Army enlistees come from military families, with about 30% having a parent who served. This trend is creating a “warrior caste,” where military service becomes a family tradition rather than a national duty. This is dangerous for democracy because it isolates the military from the general population, leading to less public oversight and accountability.
The recruitment crisis could become a bigger threat to U.S. national security than any of the conflicts making headlines. If this issue isn’t addressed, the U.S. military risks shrinking to a point where it can no longer sustain its global commitments. While some suggest relaxing recruitment standards for specialized fields like cyber operations, others warn that this could undermine the military’s core values.
As global tensions rise, the U.S. needs a capable military more than ever. Whether the solution lies in new marketing strategies, structural reforms, or even a return to conscription, it’s clear that action is needed. Without enough troops, the U.S. risks losing its standing as a global military power—an outcome that would have far-reaching consequences for national security.
