I take it this area is safe for digging?
"Wot's this metal thingy here?" (giving it a bash with his shovel/crowbar/pickaxe).
"Oh well, that's got us a few feet deeper!"
Though I suppose most of the stuff fired from the tank guns at Castlemartin will be solid shot...
Not always, Chieftain's, Challenger's and the German Leopard's, can fire a variety of rounds, not just A.P.D.S. (solid shot-rather like an arrow), but H.E.S.H. ( Hi. Ex. Squash Head.) which is several Kilo's of bang,& Std. Hi. Ex., Canister Rounds (which converts a tank gun into a shot gun), + Smoke rounds, from both the main gun, and grenade launchers, which may contain White Phosphorous,,,,,VERY NASTY, Then there's the small calibre rounds from the machine guns, some of which (1in4) will be tracers, and the Chieftain used to use a .50 cal "Ranging Gun", which fired a 1/2" Flashing tip incendiary round, to lay the Main Gun.
My former employers also used to drop things there, like 28lb. Practice bombs which contain a W.P. smoke charge, and they don't always go off, they can lie buried for years, quite safe until disturbed. Cluster Bombs may also have been dropped, 147 mini-bomblets, often, not all of which go off. They cannot be defused, and could go at the slightest touch. S.N.E.B., Air to Ground Rockets will almost certainly have been used too, and as before, they don't always go off either. The same can also be said for the "Charley G ", 84mm Rocket Launcher, and the 66mm, and the 90mil, and also the MILAN wire guided Missile, to name but a few. A pattern is emerging here,,,, Not Everything Goes Off as advertised on the box.
One final thing to think about is the MoD.'s Paperwork obsession, especially when it comes to issuing Ammunition. In short, Because of the packaging that ammo comes in, all of which is discarded before use, it's bloody nigh impossible to put it back into stores, the form filling alone is phenomenal. Once issued, it has to be used.To avoid this bullshit, yer average Squaddie (and Airman in my case), will generally employ "Alternative Disposal Methods", ie: Dump it. Now your Chieftain and Challenger's main Armament is a 120mm gun that uses "Bagged Charges" , that's a sodding great bag of Cordite as a propellant, rather than a Shell Case, so no empties to get rid of. They are not always "Flared Off" at the end of practice, so these buggers can often be found just below the surface, and Cordite can remain viable for decades
In summary, I wouldn't dig there.
