THE FATHER OF AN ARMY VETERAN CHARGED WITH JOINING FORCES WITH AL QEADA ... SAYS HIS SON IS AS PATRIOTIC AS ANY OTHER SOLDIER.

[Notes:SOUNDBITE Darryl Harroun, Father: "I think it's funny. Anybody that knows Eric, knows that he's 100 percent American."]

30-YEAR ERIC HARROUN SPENT THE PAST FEW MONTHS IN SYRIA ...

THAT'S CLEAR FROM A QUICK GLANCE AT HIS FACEBOOK PAGE..

BECAUSE IT'S HERE WHERE THE PHOENIX NATIVE BOASTED ABOUT MILITARY ADVENTURES WITH SYRIAN REBELS...

ACCORDING TO AN FBI AFFIDAVIT, HARROUN CROSSED THE BORDER INTO SYRIA IN JANUARY ... MAKING CONTACT WITH A REBEL GROUP CALLED THE FREE SYRIAN ARMY.

THE U-S LISTS THEM AS A TERORRIST GROUP.

ON HIS FACEBOOK PAGE HARROUN CLAIMS HE USED R-P-G LAUNCHERS ...

BACK IN ARIZONA ... HIS FATHER SAYS NO WAY.

[Notes:SOUNDBITE Darryl Harroun, Father: "He was trying to save you know lives and what not. But he's not you know any kind of a terrorist or anything."]

HARROUN FLEW BACK TO THE U-S WEDNESDAY ...

F-B-I AGENTS ARRESTED HIM IN VIRGINIA AFTER QUESTIONING.

[Notes:SOUNDBITE Darryl Harroun, Father: "I don't understand the charges what not."]

HE'S CHARGED WITH CONSPIRING TO USE A WEAPON OF MASS DESTRUCTION

HE NOW FACES UP TO LIFE IN PRISON.
