Weapons
At first, the soldiers of HYDRA were armed with standard weapons of the German armed forces of World War II. Many HYDRA troopers were armed with the MP 40 submachine guns. Johann Schmidt himself used the Luger P08. HYDRA's assassins like Heinz Kruger were armed with the Walther P38s. HYDRA's sharpshooters were armed with Mauser Karabiners.
Even before they harnessed the power of the Tesseract, the scientists of HYDRA developed several advanced weapons, like the flamethrower. But with the power of the Tesseract, the HYDRA scientists invented the advanced rifles, pistols, and cannons. These weapons were able to vaporize HYDRA's enemies in a single shot in battle.
Equipment
HYDRA used a variety of advanced vehicles. Thanks to the scientists like Arnim Zola, members of HYDRA could rely on armored vehicles equipped with flamethrowers, armored personnel carriers, experimental planes, futuristic exo-skeleton battle suits, submarines, gigantic tanks, flying bombs, motorbikes, and giant vehicles like the Leviathan submarine or the Valkyrie bomber.
Uniforms
As the SS divison, HYDRA mostly used the standard grey and black uniforms of the Schutzstaffel. They also used the standard German Stahlhelm helmets. Their ranks insignia was identical to that of the SS. However, to distinct themselves from other SS units, they wore HYDRA badges on their caps and collars, instead of the SS rune patches and Totenkopf badges. They also had HYDRA patches on the upper parts of their sleeves. Some members of HYDRA also used armbands similar to those of the Nazi party. However, their armbands had the HYDRA logo instead of the swastika. Some HYDRA helmets had no insignia, but others had German Imperial tricolor shield decals and HYDRA shield decal.
Over the time, HYDRA adopted another type of uniforms. The new uniforms were green, and of completely unique design. The new uniform also had HYDRA patches on sleeves.
