Shocking figures show that in the past ten years there have been 111 cases of military personnel possessing vile child porn images.
Military Police lead a detailed investigation into the problem with a dedicated team that hauled alleged offenders before court, with 64 personnel pleading guilty.
Of those 64, nine were convicted and four acquitted.
In total, 12 cases were opened by the Service Prosecution Authority last year alone.
An MOD spokesperson said: ‘Viewing indecent images of children is an abhorrent crime’
The scale of the problem was revealed in figures obtained by The Sun on Sunday under Freedom of Information laws.
The year that saw the most cases was 2009, with 17 referred to the SPA and 13 guilty pleas. However, there were only two convictions that year.
Data collected from the Army Prosecution Authority, RAF Prosecution Authority and the Navy Prosecution Authority showed that in 2016 there were three convictions, the most in the past 10 years.
A Royal Air Force Serviceman, Corporal Roger Heal, was charged for the alleged possession and distribution of indecent images of children in 2015.
Investigators believed that the he had contact with children through his voluntary work for youth organisations, including the Scouts, Air Cadets and civilian football and cricket clubs, predominantly in the areas of London, Thames Valley, Cheshire and Northumbria, between 2001 and 2014.
It is thought that he was jailed for 15 months and discharged from the forces after being arrested at RAF Waddington in Lincolnshire.
In another case a sergeant with the RAF at Henlow, Beds, was thrown out of the service and jailed for 32 months.
Colonel Richard Kemp said: ‘The military is drawn from society and this is a major problem generally’
Colonel Richard Kemp, former commander of British forces in Afghanistan, told The Sun: ‘The military is drawn from society and this is a major problem generally.
‘This shows the forces are tackling this and rooting it out.’
An MOD spokesperson said: ‘Viewing indecent images of children is an abhorrent crime and has no place in the Armed Forces.
‘Any individual found to be guilty of such despicable conduct can expect to be discharged.’
