The biggest booms
Building bridges under fire, storming enemy fortifications, planting mines, playing with explosives, designing friendly fortifications--lots of these tasks sound crazy, but they are the combat engineer's bread and butter. Engineering battalions have long been a fixture of European armies, but the Second World War and Germany's Blitzkrieg tactics brought about a greater need for them than ever before. Quick movement of massive forces required dedicated troops willing to advance under fire, clear or bridge obstacles, and simultaneously maintain any German defenses. Kit features forty German engineer figures.
