Armoured bus
An armoured bus or armored bus is a type of bus which provides increased protection for passengers, usually against small arms and improvised explosive devices. The bus can be a stock commercial bus with retro-fitted vehicle armour as well as bulletproof glass, or a specially built military armoured vehicle. Lighter armoured buses are also used for prisoner transport.
History
One of the first armored vehicles to be used in combat was the Schneider-Brillié which was built from the chassis of a Schneider P2-4000 busDuring World War I, civilian buses were pressed into service, especially by Great Britain and France, fulfilling several roles: to transport troops, supplies, and livestock, and as ambulances and mobile surgeries. Britain used several hundred Daimler and LGOC B-type buses as troop transports, but they were not armoured. It was found that the windows were frequently broken by troops' equipment, and the glass was eventually removed. Wooden planks were fixed over the apertures, offering protection from the weather but not from hostile fire.
Armoured buses weigh considerably more than ordinary buses. As a result, they use more fuel, are prone to mechanical breakdowns, have very high maintenance costs and wear out faster.
