with only a few working prototypes the chances of getting behind the sticks of a chally are looking far off for a good many years until they declassify chobham
looking at those photos brings back the stark differences between challenger one and two i remember two had hydrogas suspension on the photo it looks like its fitted with chieftain style spring packs, the hydrogas was always interesting when the attached infantry tried camping under our wagon after a days flying about salisbury plain they didnt realise as the suspension cooled the ride height got lower so they crawled nice and easy under at night but were very nearly stuck in the morning needing pulling out by their dos bags, only then did the horror stories start and no one ever slept under or near the tracks of a wagon again, my favorite spot was a dip in the armour on the right hand side of the gun sponson where the gunners sight was that dip was made for sleeping in, on exercise we had a guy come off radio stag and walk off the back of the turret expecting a metre or so drop onto the engine deck, the guy completely forgot we had the gun over the side and landed on the stumpy sa80 cocking handle right in his ribs. silly bugger
