Youngest Most At Risk
While the risk of suicide among British armed forces personnel is lower than that found in civilian life, this is not so among the youngest soldiers, who are much more likely than their civilian peers to end their lives. The risk is highest of all in child recruits who leave soon after joining.
1.1 Youngest Recruits
Over the last 20 years, suicide in the British armed forces has been less common than among civilians of the same age. 45 This is not so for male soldiers aged 16–19, whose risk has been one-third (31%) higher than that of same-age civilians46 and three times the average for the armed forces as a whole.47
This high risk is mostly confined to the army; the risk to young air force and navy personnel has resembled that faced by civilians of the same age.48
Figure 1 shows how high the risk has been for young soldiers. The bold horizontal line in each graph shows the suicide rate in the general population for the same age group; the red line shows the rate in the army. The first graph shows the suicide rate since 2001 in the under-20 age group.

1.2 Women and Girls
Since female personnel are a small minority of the armed forces, calculating their suicide rate reliably is not possible.51 Suicide among female former personnel (i.e. 'veterans') follows a similar pattern to men: overall, the risk is little different from civilian life, but among the youngest it is between three and four times higher.52
The experience of other countries suggests that, in general, female personnel and veterans are at increased risk relative to their civilian peers, though less is known about the specific risks of younger age groups:
- In the United States, whose armed forces are large enough to calculate a rate of suicide among serving female personnel, their risk is approximately twice that of civilian women.53
- In Australia and Canada, female veterans have been around twice as likely as their civilian peers to end their lives,54 and in the United States three times as likely.55
Given the dearth of data on female or transgender military suicide in the UK, the rest of this report focuses on the risk among males.
1.3 Infantry
As mentioned, youth suicide risk in the armed forces is concentrated in the army. Within the army, it is concentrated in the infantry. These are close-combat troops who make up just over a quarter of army personnel.
The army says that the reason it recruits soldiers from age 16 is ‘particularly for the infantry’56 and child recruits are indeed over-represented among infanteers.57

Infanteers have a very high suicide risk (Figure 2), which is concentrated in soldiers who signed up as children: over half of infanteers who died by suicide in the last two decades joined up under age 18 (Figure 3).59 Between 2001 and 2020, infanteers who had joined up under the age of 18 had more than double the odds of in-service suicide as soldiers who had joined up as adults [OR 2.3, 95% CI 1.4-3.7, p=0.001].60
1.4 Youngest Veterans
![Figure 4](https://images.squarespace-cdn.com/content/v1/5afadb22e17ba3eddf90c02f/b67f8702-6e9f-4b96-bafa-6ecd77744d4c/Figure+4+%28New%29.png?format=2500w)
The risk of suicide and other mental health problems increases after personnel leave. In around the last two decades, the youngest veterans – which here means all ex-personnel, whether they have been to war or not – have been three times as likely as same-age civilians to end their lives.62
Figure 4 presents the findings of the study in question, showing how strongly the risk of veteran suicide is concentrated among the youngest. The dotted line shows the civilian suicide rate for each age group; the purple column shows the rate of suicide in the youngest veterans.
In an earlier study by the same team, veterans who had both joined up and left at 16 had had the highest suicide risk of all.63 Evidently, child recruits who leave service early – which usually means during their initial training – face a markedly elevated risk of suicidality.
1.5 International Comparison
A similar pattern is seen in other economically comparable countries that enlist child recruits (Figure 5).65 As in the UK, so in Australia, Canada, and the United States, the risk is concentrated in the army and especially army veterans.66, 67
In respect of serving personnel, research in the US found that many more attempted suicides in the US Army were by soldiers in training than by those at war.68 In respect of veterans, other research in the US found that veterans with less than one year’s service – who tend to be those who dropped out of their training – were much more likely than longer-serving veterans to end their lives.69 As in the UK, so in Canada and the US (though not in Australia), most cases of veteran suicide occur in the few years after discharge.70

Alison's Story
Alison’s son Nathan joined the Army Foundation College in 2016, aged 16.
Nathan started his military career at the
Army Foundation College Harrogate in
2016. Nathan was a confident, resilient
lad who wanted nothing more than to be
a soldier. [...] During the first phase of his
training Nathan reported serious incidents
to me; he told me he was hit, slapped,
pushed, kicked and verbally abused by staff.
He said he felt humiliated... He knew the
training would be tough but this was abuse
and the staff were power crazy. [...]
Nathan felt uncomfortable talking about
what was happening to him but I often
pushed him to open up and talk to me.
He did tell me about witnessing abuse of
his peers and commented on his dislike
and distrust for some of the staff. He did
however point out not all staff were abusive
but said that none of them could be trusted.
He told me all staff knew what was going
on but turned a blind eye. [...]
After the initial six weeks of training we
travelled to Harrogate for Nathan’s first
passing out parade and brought him
home on leave. He was not the same
happy confident lad who started six weeks
previously. He started drinking heavily and
was very withdrawn. It was very difficult
getting him to return to Harrogate and he
told me he wanted to leave the army.
When he returned to Harrogate, he rang
me to tell me he was handing in his letter
to leave. He told me his request was ripped
up in his face. He was only 17 years old
and devastated at not being able to leave.
He repeatedly told me he wanted to be a
soldier and expected training to be tough
but couldn't cope with the way they were
mistreated. He was clearly very frightened
for his safety and I shared his fears.
Whenever he was on leave it became
increasingly difficult to get him to return
to Harrogate. I would take him to the train
station and by the time I arrived home
Nathan wouldn't be far behind me. He was
genuinely very fearful of being at Harrogate
and things just got worse... He didn't mind
the legitimate punishments, it was the
abuse he was scared of.
I spoke to his commanding officers after
every occasion and expressed my concerns.
Each member of staff basically said the
same thing: if Nathan didn't return he would
be posted AWOL. I was repeatedly told
[incorrectly] that once he had completed
the first six weeks he had no way of leaving.
They said no matter how he felt he had to
complete the four years. [...] The officers
told me that if Nathan didn't return then the
seriousness of the situation would escalate
and the punishments would be more severe.
[...] He described the staff as animals that
got off on hurting and humiliating people
and that Harrogate should be shut down.
Nathan died while still serving in the army.

UK MoD, 2022b, op cit., Additional Table 4.
48 The suicide rate in young personnel relative to same-age general population between 2002 and 2021 has been 51% lower than the same-age general population in the air force and 1% lower in the navy. The relatively higher rate found in the navy could be due in part to marine commandos, who make up its intensively trained, ground close-combat arm. Ibid.
