Spanish troops fire a 155mm self-propelled howitzer during a drill in
the training fields of San Gregorio near Zaragoza June 3, 2002. The
Spanish army along with U.S Marines, Hungarian, French, Dutch and
German troops are participating in a NATO exercise labeled "Dynamic
Mix" where participating countries pretend that one of its allies, in
this case Spain, is being attacked by a fictitious country.
