As it says on the Peace Arch between Canada and the USA.
Gunners and Sappers were born from the Board of Ordnance and definitely share many bonds- big booms, St Barbara, Ubique!, the ability to read and write

and a love for big forts with "biguns" in 'em.
One small observation: a Gun/Skyguard Section was two guns (GDF 005 twin 35mm Oerlikons) and a radar trailer (Skyguard system). Two Sections made a Troop and two Troops made a Battery. Imagine THAT noise level!
