Commando Comic #4450 'The Nightmare War' (2011)
 
Private Franz Bauer, a German Army engineer wounded during the invasion of France, was haunted by the deaths of his comrades in the same battle - wiped out by a mine. When he recovered he threw himself into his new job developing the remote-controlled Borgward IV demolition vehicle, hoping it might save other German lives.
 
His chance to save thousands of lives would come, but he would be working alongside an unlikely ally - someone who had nightmares every bit as bad as Franz's.
