How WWII Marines used spikes and concrete to protect their tanks
During the Pacific campaign of World War II, tank crews could not always wait for official upgrades. This video explores the improvised, often strange battlefield modifications used to defend Sherman tanks from enemy infantry.
Facing unique threats in the Pacific, US Marines implemented DIY armor solutions. To prevent soldiers from climbing onto tanks to plant explosives, crews covered their Shermans in metal spikes. Beyond these spikes, crews also added layers of wood, spare tracks, and even concrete to provide extra protection. While these makeshift defenses sometimes proved effective, they could also cause significant damage to the tanks themselves.
