True, but the Zero/Reisen did have a much more lighter armour than other fighters. A few shots anywhere on it would take it out, so a quick snapshot could take it out rather than just damage another, heavier plane. It would be more vulnerable to any shots, as a result of the armour, small arms included. One was shot down with a BAR from a C-47 once. I think the elevators would lock up if the Zero/Reisen went to fast though. It was one of the best carrier fighters of WW2 with a 12:1 Kill ratio as a result of its legendary manoeuvrability though.
