I have a great great Uncle buried in Flanders Feild, he was an RAF pilot and was killed in action by Rittmeister von Richthofen (AKA the Red Baron)
My grandfather on my mothers side served in WWII (A navy pilot And was present for Pearl Harbor), Korea (Army Pilot), and Vietnam (Pilot Instructor)
Both my uncles served in Vietnam as well, one was a Seaman on the USS Ticonderoga (He was serving when the Air Craft carrier recovered the Astronauts from Apollo 17), the other was a Gunnery Sargent in the Marine Corps.
On my fathers side, My grandfather was in the Merchant Marines, ferrying supplies from Canada to the UK during WWII, two of the three ships he served on were sunk by German U-Boats.
And Lastly, my father served in the Canadian Military for 25 years, he dealt in Digital Communications and Encryption, did a NATO tour in Germany back in the 80s, he also served 2 peace keeping tours in Bosnia.
I also have a great many friends who are currently serving. I've also lost 6 of them in Afghanistan.
The only person I know in my family that fought in the past was my great great grandfather he fought for Mexico in the war on Texas but he was killed when a cannon blow his head off.
I'm really sorry about what happen to your friends.
I have some friends in Afghanistan and some that want to go.
I really do wish the rest of your friend to best of luck over there and I hope my friend can make it out ok too.
I'm really sick of hearing about my friends being killed.
