Sterlings are useful and appreciated for.
a) Sappers, RAME, RMP (with head swaps) and all sorts of odds and sods and hangers on that can still be incorporated into a platoon plus sized game.
b) 1960s infantry where use of the Sterling by JNCOs seems to have been much more of a thing, at least period photos seem to suggest as much. Shave off the right trouser pocket, remove the sleeve pocket on the jacket, paint green and there you have it. Chaps to defend Berlin in 1961 or repelling Jack Lynch’s mooted invasion by the Irish Army of Norn Irn in 1968.* I have a second platoon’s worth so converted.
* The aptly named Exercise/ Operation Armageddon. Look it up. Utterly bizarre and suicidal for the Irish Army, had it taken place but good gaming fodder, the Irish even get Comet tanks.
