According to a War Office training pamphlet dated 29 August 1940, the sticky bomb should be regarded as a portable demolition device which can be "quickly and easily applied".[12] It was reckoned to be effective against armour of up to one inch (25 mm) thickness and was suitable for use against "baby" tanks, armoured cars and the vulnerable points on medium and heavy tanks. The safest and easiest application was simply to drop it from an upstairs window; otherwise, it could be used in an ambush of mobile tanks moving along a narrow road or in an attack on tanks parked up for the night.[12]
