Just been given a fast ball and i dont have any Engineer type mates to ask. My Regiment is after a load of sand to build some temporary unloading bays. My QM (Tech) then asked me "what is the NSN for sand?". Now in my 22 and half years service so far, i didnt know, or even think that sand had an NSN. So a bit of help from an Engineer type guru please, how do i get hold of some sand without stealing it or driving down to Bournemouth beach to get some. They are not willing to pay for it either. Can i demand it? If so what is the NSN.
