well, I'm an old soldier. My first incarnation in gren was as a gunner on the 105s. My first job was jumping out the back of a 1 Tonny and taking the wheel off so that we could point the barrell in the right direction. It was a cnut of a job, especially when muddy, so I know that gunners need a good sense of humour.
(mind you, firing the 105 in the A/T role was a blast! )
