An MOD written parliamentary answer to James Cartlidge MP (Cons, Shadow Secretary of State for Defence) reveals that in just under 20 months, nearly sixty thousand applications to join the armed forces were rejected on medical grounds.

The answer also revealed striking disparities amongst the figures for the respective services -

Rejections per service

• Army: 45,680 rejected on medical grounds
• RAF:   12,310
• Navy:    1,020

Although not specifically stated, these figures are for regular forces. Applying them to the approximate current size of each regular force reveals a huge variation in the proportion per service of applicants rejected on medical grounds -

Rejections compared with approx service size

• Army ∼ 62% rejections as %age of current force
• RAF   ∼ 41% rejections as %age of current force
• RN/RM ∼3% rejections as %age of current force

Another way to view these figures is that the Army rejected on medical grounds around 6 applicants for every 10 serving soldiers; the RAF rejected around 4 applicants per 10 serving aviators, and the RN/RM rejected less than one applicant per 10 serving sailors or marines.

Comparing the medical rejection figures with annual targets, however, shows the Army and the RAF rejecting about the same percentage on medical grounds, with the RN/RM rjecting far fewer -

Medical rejections compared with target recruitment intake

• Army - around 2.7 rejections per target recruit
• RAF - around 2.6 rejections per target
