@Robert Gentel,
Vietnam, depending on the source between 980,000 - 1,100,000 Vietnamese - north and south.
Cambodia - no number due to heavy genocide killings
Invasion of Dominican Republic - ca. 2500
Invasion of Grenada - ca. 70 (Cubans included)
Libya 1986 - ca. 45
Invasion of Panama - ca. 300
Gulf war - 35,000
Iraqi - no-fly-zone - unknown
Bombing of Afghanistan/Sudan 1998 - 7
NATO war in Kosovo - can't give an accurante number
Iraq war - 600,000
Afghanistan - NATO war, hard to give exact numbers who was killed, I guess at 20,000
There are additional involvements in the Philippines, Libya (2011), the "war on terror" involving many other countries, as well as other NATO (Kosovo etc.) wars. I am sure I left out some...
