Brings back mixed memories. 4 Field, Medium Battery, Airborne Artillery. Those G5 projectiles were my nemisis. Grab one of those over your shoulder and run a few km's will reduce even the strongest man to tears.
That last vehicle/pic was my office. The TA used to calculate the range and elevation and feed the co-ordinates to the gunners. Our vehicle was not quite as sexy as that. Ours was a box on the back of a Unimog.
Thanks for the pics, great seeing the equipment is still serviceable.
