Dude, that's 27 more confirmed than good 'ole Hathock was credited with during his tours!
Hathock and his spotter took out an entire VC company in the course of three days, over a hundred men, leaving only one survivor. Sergeant May, like all of us interested in such things, thought/assumed those kills were confirmed.
Sergeant May (now retired) is a DSC winner. I'm sure one could look up his record, if one was so inclined.
