, the possibility of success was not quite as distant as might be imagined. 1940 was at the very end of the era of the light tank and the German behemoths of the later war years were still in the future: many tanks were surprisingly vulnerable.

When used in the right way and in sufficient numbers the Finns had found that they were effective. Although the experience of the Spanish Civil War received more publicity, the more sophisticated petroleum warfare tactics of the Finns were not lost on British commanders.

 said:
Wintringham advised that a tank that was isolated from supporting infantry was potentially vulnerable to men who had the required determination and cunning to get close. Rifles or even a shotgun would be sufficient to persuade the crew to close all the hatches and then the view from the tank is very limited; a turret mounted machine gun has a very slow traverse and cannot hope to fend off attackers coming from all directions. Once sufficiently close, it is possible to hide where the tank’s gunner cannot see: “The most dangerous distance away from a tank is 200 yards; the safest distance is six inches.” Petrol bombs will soon produce a pall of blinding smoke and a well placed explosive package or even a stout iron bar in the tracks can immobilise the vehicle leaving it at the mercy of further petrol bombs – which will suffocate the engine and possibly the crew – or an explosive charge or anti-tank mine.

The instructions suggested scoring the bottles vertically with a diamond to ensure breakage and providing fuel soaked rag, windproof matches or a length of cinema film (made of highly flammable nitrocellulose) as a source of ignition.

On 29 July 1940, manufacturers Albright & Wilson of Oldbury demonstrated to the RAF how their white phosphorus could be used to ignite incendiary bombs. The demonstration involved throwing glass bottles containing a mixture of petrol and phosphorus

 at pieces of wood and into a hut. On breaking, the phosphorus was exposed to the air and spontaneously ignited; the petrol also burned resulting in a fierce fire. Because of safety concerns, the RAF was not interested in white phosphorus as a source of ignition, but the idea of a self-igniting petrol bomb took hold. Initially known as an A.W. bomb, it was officially named the No 76 Grenade

: "There was some concern that, if the tank drivers could not pull up quickly enough and hop out, they were likely to be frizzled to death, but after looking at the bottles they said they would be happy to take a chance." The drivers were proved right, trials on modern British tanks confirmed that Molotov and SIP grenades caused the occupants of the tanks "no inconvenience whatsoever".

Modern use

While Molotov cocktails may be a psychologically effective method of disabling armoured fighting vehicles by forcing the crew out or damaging external components, most modern tanks cannot be physically destroyed or rendered completely inoperable by Molotov cocktails; only "disabled".

, and these materials have melting points well above the burning temperature of gasoline, which makes the vehicles themselves invulnerable to Molotov cocktails. Only external components such as optical systems, antennas, externally-mounted weapons systems or ventilation ports and openings can be damaged, which can make a tank virtually "blind" or allow burning gasoline to seep into the vehicle, forcing the crew to at least open the hatches or perhaps abandon the vehicle. A molotov cocktail thrown through an open hatch into the crew spaces would, like most other grenades, seriously affect the crew and equipment. However, many modern tanks (such as those operated by the US and NATO) have onboard fire suppression systems. Any fire in a crew space will be automatically extinguished with Halon or another fire suppressant.
