Tag-Along
An alias employed by Superman after a powerful bomb explodes that not only sends Superman back into the past during WWII but also gave him total amnesia.
In this past, he finds an American soldier uniform and dons it to hide his regular costume since he is no position to explain it. Unfortunately, he soon encounters Sgt. Rock and Easy Company who had just dealt with Germans impersonating US soldiers and suspected that this stranger was one of those imposters considering he has no identification such as military dog-tags. As it happens, this confrontation was interrupted by Sgt. Rock spotting Germans lying in ambush and Easy Company defeats them which leads them to believe that the stranger is not one of them since the enemy made no attempt to give him preferential treatment.
After the incident, Easy Company takes Clark along and question him with American culture trivia like baseball results and are satisfied when he answered correctly. As a result, Rock follows the company's tradition and dubs the stranger a distinctive nickname, Tag-Along. Their new addition becomes a mixed blessing for Easy Company, one example being when a German tank attacks them. Tag-Along has the unit's anti-tank weapon, but Clark's forgotten vow never to take a life subconciously prevents him from firing it despite the fact that his comrades are in deadly peril. Fortunately, when Clark pounds the ground in frustration, he inadvertantly creates an earthquake with the shockwaves, creating a fissure that the tank falls into which allows Easy Company to destroy it.
Shortly, Superman's memory returns and he resolves to protect Easy Company for a short time, first from an attacking war plane and then, by destroying a Nazi outpost before faking his death to fool the company. Allowing himself to be buried, Superman digs himself out and returns to the present day.
