Armys

The United States army announced last month that it would raise the maximum age at which Americans can enlist from 35 to 42 years to expand its pool of eligible candidates amid recruiting challenges in recent years.

An updated version of US Army Regulation 601–210, dated March 20, outlined the changes, including the elimination of rules requiring anyone with a single conviction for marijuana possession or drug paraphernalia to obtain a waiver to enlist.

Government data shows that while the US army has met its recruitment goals over the last two years, it fell short in 2022 and 2023 and has consistently failed to meet targets for the Army Reserve, shortcomings that analysts have attributed to several possible factors.

The new age limit was announced during the US-Israel war on Iran, towards which young people have expressed widespread opposition.

Here’s what you need to know about the changes.

When does the regulation go into effect?

The updated version of Army Regulation 601–210 officially takes effect on Monday, April 20.

What has the military said about the changes?

The US army announced updated enlistment regulations on March 20, with the changes scheduled to take effect one month later on April 20 and applying to the Regular Army, Army Reserve, and Army National Guard.

The maximum enlistment age is raised from 35 to 42, and previous restrictions requiring anyone with a single conviction for possession of marijuana or drug paraphernalia to obtain a waiver to enlist are done away with.

Do these changes apply to the whole US military?

The changes announced in March are specific to the US army.

The military news outlet Stars and Stripes reported that those changes bring the army into greater alignment with the maximum enlistment age of other branches of the military, such as the Air Force, Navy, Coast Guard, and Space Force, which accept enlistees in their early 40s.

The maximum enlistment age for the US Marines is 28.

What factors explain the change?

While the US army did not comment on the reasons for the increase, data from the US Army Recruiting Command show that the army has struggled with recruitment challenges.

While the army met 100 percent of its recruitment goals in 2025 and 2024, it missed its target by about 23 percent in 2023 and 25 percent in 2022.

That data also shows that the army has fallen short of recruitment targets for the Army Reserve for the last six years in a row.

The average age of army recruits has risen in recent years to 22.7, up from 21.7 in the 2000s and 21.1 in the 2010s, according to the military news outlet Army Times, citing data from a US army spokesperson.

The US Army Recruiting Command has attributed such challenges to issues such as changes in the labour market, limited awareness about military service, and a lack of qualified young people due to issues such as obesity, drug use, and mental health issues.

A 2018 poll listed concerns over possible injury and death, post-traumatic stress disorder (PTSD), separation from family and friends, and other career interests as top reasons offered by young people for not joining the military.

Does the change have to do with the war in Iran?

Analysts have been discussing the possibility of raising the enlistment age for years as a means of addressing recruiting challenges, with a 2023 research report from the RAND Corporation, a US think tank, calling “older youth” a “crucial, largely untapped, yet high-quality pool of potential recruits”.

While the military has not suggested that the change is linked to the US-Israel war on Iran, where US President Donald Trump has previously said he could deploy ground troops, some social media users were quick to note the timing of the announcement.

Some in the online community joked that older supporters of the war would now be available to enlist.

“They raised the enlistment age to 42,” one X user said in response to a video of the conservative commentator Ben Shapiro praising Trump’s decision to attack Iran. “Why are you still here?”

Surveys have found that younger people are more likely to oppose the US war on Iran than those aged 65 and up, and polls in recent years have found that young people are more generally sceptical of US intervention abroad than older generations.

A 2024 Pew Research Center poll found that people between the ages of 18 and 29 were the only age bracket in the US who viewed the military more negatively than positively, with 53 percent saying the military had a negative effect versus 43 percent who said it had a positive effect.

How many people are currently in the US military?

According to the Pew Research Center, the US military has about 1.32 million active members. The US army accounts for the largest share, with nearly 450,000, while the US Navy is second with more than 334,000.

The Air Force has more than 317,000, the Marines more than 168,000, the Coast Guard nearly 42,000, and the Space Force nearly 9,700.

Data from the US Army Recruiting Command shows that about 80 percent of recruits in the Regular Army were men in 2025.

Black and Latino recruits also make up a larger share of army recruits than their percentage of the population, each making up about 27 percent of recruits while comprising 14 percent and 20 percent of the general population, according to data from the 2024 census.

White people made up about 40 percent of US army recruits, while about 57 percent of the general population.

WASHINGTON — Defense Secretary Pete Hegseth has asked the Army’s top uniformed officer, Gen. Randy George, to step down, the Pentagon said Thursday, as the United States wages a war against Iran.

A Pentagon official, who spoke on condition of anonymity to discuss the sensitive matter, confirmed that George has been asked to take early retirement from the post of Army chief of staff, which he has held since August 2023.

The ouster of George is just the latest of more than a dozen firings of top generals and admirals by Hegseth since he first took office last year.

CBS News was first to report the ouster.

George is a graduate of West Point Military Academy and an infantry officer who served in the first Gulf War as well as Iraq and Afghanistan. He also served as Defense Secretary Lloyd Austin’s top military aide from 2021 to 2022, during the Biden administration, before taking on top leadership roles in the Army.

George survived the initial round of firings last February, which saw the removal of top military leaders, including Adm. Lisa Franchetti, the Navy’s top uniformed officer, and Gen. Jim Silfe, the No. 2 leader at the Air Force, by Hegseth. President Donald Trump also fired Gen. Charles “C.Q.” Brown, then the Chairman of the Joint Chiefs of Staff, at the same time.

Since then, more than a dozen other top military generals and admirals have either retired early or been removed from their posts.

Among these departures was George’s deputy, the Vice Chief of Staff of the Army, Gen. James Mingus, who was in the post for less than two years when Trump suddenly nominated Lt. Gen. Christopher LaNeve for the position. LaNeve was then serving as Hegseth’s top military aide, having been plucked for that post from commanding the Eighth Army in South Korea after less than a year in the job.
