Corporal McCarthy was assigned to RAF Brize Norton in July 2009 where he volunteered to deploy with 174 Provost Company, 3rd Regiment Royal Military Police as part of the Theatre Provost Group.
During his pre-deployment training Corporal McCarthy showed an aptitude for mentoring and was a natural choice to embed with the Welsh Guards as part of the Police Mentoring Advisory Group.
Corporal McCarthy leaves behind his father John, mother Sarah, sister Jodie, his partner Sarah and his niece Miajay and nephew Kyron.
