Commander, Royal Artillery (abbreviated CRA) was a military appointment in Commonwealth infantry and armoured divisions in the 20th century. The CRA was the senior artillery officer in the division and commanded the regiments of field, anti-aircraft and anti-tank artillery, and provided specialist artillery and offensive support advice to the divisional commander. Even though the Canadians, New Zealanders, etc. had their own artillery corps (i.e. the Royal Regiment of Canadian Artillery), the term CRA was still used to mark this appointment in formations of those armies (rather than CRCA or CRNZA etc.) for consistency between the allies. The CRA was ranked as a brigadier general in the First World War, and as a brigadier in the Second World War.
