I taught myself how to calculate weighted averages this afternoon so I could find out the average age of Canadian, American and British personnel killed in Afghanistan and Iraq.
FWIW, based on my calculations:
CDN: 29.8 years - most common rank: corporal (Afghanistan only)
US: 28.7 years (Afghanistan), 26.1 years (Iraq) - most common rank: sergeant/staff sergeant (Afghanistan), specialist (US Army)/lance corporal (USMC) (Iraq)
UK: 28.2 years (Afghanistan & Iraq) - most common rank: lance corporal (equivalent to CDN corporal/US sergeant)
