The report, issued last week by the Joseph Rowntree Charitable Trust, claimed that children as young as seven have been targeted by armed forces recruitment campaigns.
The report's writer, independent analyst David Gee, said the armed forces used 'PR tactics' such as visiting depressed towns with fewer opportunities, placing computer games simulating driving tanks on its website and sending regular mail-outs to potential recruits.
However, the MoD has dubbed the report 'incorrect and ill-informed'.
An MoD spokeswoman said: 'Our recruitment practices avoid glamorising war and we refute any allegation that they depict warfare as game-like. Anyone considering a career in the armed forces is presented with clear information and all aspects of service life are discussed in detail, following a sensitive recruitment process.'
