The First Air War
In 1914-1918 military aviation evolved from a novelty to an essential combat arm including
reconnaissance, air superiority, tactical support of ground operations, and strategic bombing.
The First U-boat War
Unproven in 1914, submarines almost became the decisive weapon of the Great War as
Germany countered the Royal Navy’s blockade with its near-successful U-boat campaign
against the shipping that supplied Britain.
The First Tank War
The armored, caterpillar-tractioned fighting vehicle was developed in World War I to
break the trench warfare stalemate, and was first used in 1916’s Battle of the Somme.
