The Pickelhaube, also Pickelhelm, is a spiked leather or metal helmet that was worn in the 19th and 20th centuries by Prussian and German soldiers of all ranks, firefighters and police. Although it is typically associated with the Prussian Army, which adopted it in 1842–43, the helmet was widely imitated by other armies during that period. It is still worn today as part of ceremonial wear in the militaries of certain countries, such as Sweden, Chile, and Colombia.

A shako is a tall, cylindrical military cap, usually with a visor, and sometimes tapered at the top. It is usually adorned with an ornamental plate or badge on the front, metallic or otherwise; and often has a feather, hackle, or pompom attached at the top.
