General Sir William Green, 1st Baronet, of Marass, Kent was an officer in the British Army.

The Soldier Artificer Company was a unit of the British Army raised in Gibraltar in 1772 to work on improving the fortifications there. It was the Army's first unit of military artificers and labourers – the existing Corps of Engineers was entirely made up of commissioned officers – and it replaced the traditional but unreliable practice of employing civilian craftsmen. The company was an immediate success and was responsible for upgrading the British fortress's defences before the Great Siege of Gibraltar.
