A name given to Provisional Irish Republican Snipers capable of getting one shot kills on British Soldiers. Most snipers were from Corssmaglen. Most Crossmaglen Snipers used the US made Barrett M90, Barret M82 .50 BMG rifles and the Belgian made Fabrique Nationale (FN) FAL with a high powered rifle scope.
The Brits are getting worried of Óglaigh na hÉireann if One Shot Paddy sees them, they know they are going down.
