A veteran soldier, especially one who has served long in an army; also, a devoted fan of war games or military history.
From French 'grognard,' literally 'grumbler' or 'growler,' from 'grogner' (to grumble), referring to Napoleon's tough, experienced soldiers who would grumble but remain loyal.
Napoleon's grognards were so famous for complaining yet staying faithful that the French term became synonymous with the elite Imperial Guard—now it lives on in gaming culture as a term for dedicated hobbyists!
