On the other hand, the reaction of phosphorus with air is also conducive to the outbreak of a fire, and grenade No 77 smoke grenade can also be used to destroy the tube of an artillery cannon.
This smoke grenade is used from 1943 to 1945 and especially during the Battle of Normandy. The metal used to contain the phosphorus was quickly wasted and in 1948 the remaining stock of No 77 grenades was destroyed as they were considered obsolete. Canadians produced it until 1950, using better quality metals.
