I have immense respects for aces and honest soldiers on all sides. He was quite badly wounded too.
Far from being "just another veteran", Carius was arguably the last living tank ace, at least certainly the last living man with more than 100 tank kills.
This also reminds me that there is only one submarine ace left alive on this planet today (Reinhardt Hardegen, who is 102 years old)
Losing every veteran is equally sad of course - everybody fought and suffered. But I treat figures like this as sort of milestones in our collective memory.
