These handbooks were issued to all field units in contact with the enemy in Europe and Africa, and were intended for use by all personnel to help them recognise enemy ammunition. Specialist personnel were then trained to handle and disarm/destroy the ammunition so found. Each pamphlet covers a number of items, and this issue covers a range of fuses together with German 5cm mortar bombs, the 10 cm streamlined shell (the Gr. 19 for the K18 and long 10cm guns), the 17cm QF cartridge and the 20cm spigot mortar bomb.
