WASHINGTON, Oct 18: US soldiers who staged a mutiny and refused to go on a convoy in Iraq felt commanders ignored their plight when they complained about the safety and condition of their vehicles, their relatives said on Monday.

Ricky Shealey, father of one of 18 soldiers who face discipline for refusing an order to go on a convoy last week, said his son's commanders dismissed complaints they were being asked to transport contaminated fuel in broken-down trucks.

"The command just totally ignored them when they told them this fuel was contaminated and they were still gonna send them out on this mission with contaminated fuel. They were completely aware of this situation and I believe it's a command issue, not a soldier issue," Shealey told CBS' "Early Show." Refusal to obey orders, especially in a combat zone, is a serious military offense.

Anxious to squash any suspicion of U.S. troop morale or discipline problems in Iraq, the Army said on Sunday it was investigating the "isolated incident" and preliminary findings indicated the soldiers were worried about maintenance and safety.

FRANTIC CALL: The 18 soldiers refused to accompany fuel tankers on a supply run from southeastern Iraq to Baghdad on Wednesday, arguing the fuel was contaminated and their unarmored Vehicles were in bad shape.

The tankers had previously been carrying jet fuel and had not been cleaned before the new cargo of diesel fuel was loaded, said Teresa Hill, who received a frantic telephone message from her daughter Spec. Amber McClenny.

"Hi mom, this is Amber. This is a real, real big emergency. I need you to contact someone, I mean raise pure hell. We yesterday refused to go on a convoy. ... We had broken down trucks, non-armored vehicles and we were carrying contaminated fuel," said McClenny in the message aired on U.S. networks on Monday. -Reuters
