***a Ross rifle slung over his shoulder***
A super accurate straight pull rifle which often killed the shooter as well as the target. Worked great on a clean shooting range, clogged with European mud, not so well.
Disassemble, clean, reassemble. Fire! the bolt blows back and kills the rifleman.
Back in the ‘50s, the very first fact we Canadians learned in grade school about WWI was that initially, Canadian troops were equipped with the inferior Ross rifles and led by British idiots.
