Timmeh, in March of 2003 in Southern Iraq, a British Challenger tank fired on another British Challenger tank during an engagement with the enemy, killing 2 soldiers. A British military spokesman said "Regardless of the careful planning and measures taken in the type of operations in which we are engaged and in the heat of battle there is always a risk that incidents such as this might happen."

Friendly fire accidents are a problem for ANY country's armed forces during actual combat, as people are understandably fearing for their lives and make mistakes, something most of us cannot fully understand.
