Lucky Man, Guess Who
Suppose this individual in 2009 (age 55) had a balance of 300 thousand (being generous to this army officer).
Then in 8 years his balance increased to $990 thousand i.e. by $690,000 over 8 years.
Or roughly $86,000 contribution annually.
Or effective annual salary of more than $540,000 if contribution is 16% of income.
Add to that $3000 times the number of days out of the country = at least $600,000.
Total income annually probably more than one million.
