The history of armored transportation stretches as far back as the movement of large freight. Traditionally, the smaller valuables were transported into a more’cloak and dagger’ style. Carriers would attempt to fit in with other travellers so they did not reveal the value of the freight. This strategy does not work, however, when the precious freight is large.
Early transports were caravans with armed employees. Afterwards, stagecoaches become common. They were outfitted with reinforced lockboxes while guards sat’shotgun,’ literally carrying out a shotgun for protection. This is the origin of the colloquial term currently shouted to secure rights to the front passenger seat.
World War 1 saw the first military armored transport. Tanks, armored personnel carriers, and even an armored Rolls-Royce were developed from the 1910s for its new kind of military battle. Armored cars allowed for cellular anti-aircraft guns in addition to for secure movement of precious freight. Autos blindados of those vehicles directed a Chicago company called Brink’s to start armoring college buses for carrying currency in the 1920s. The Brinks armored bus has been followed with a Model-T filled with armed guards.
Many pieces of those early armored automobiles were made from vulnerable materials. Over time, the materials used in armored transportation have shifted from wood and glass to more lasting and chemical proof material. Steel is currently the most common armor for vehicles. It is hardened by either heat treatment or by the inclusion of nickel and chromium during creation. Windows are made of thick plastic glass and bulletproof optical plastic.
