The Fireworks Code.
As the signals that are made by fireworks are always of the most important character, it is essential that the system for their use be so perfectly worked out that there will be no chance of confusion. The smaller the number of signals to be sent by fireworks, the less chance there is of confusion.
Classification of Fireworks.
The fireworks now being used by the American Army are divided into the following classes:
1. Very Pistol cartridges.
2. VB cartridges (commonly called “Tromblons”).
3. Rockets.
4. Flares.
The complete directions for firing these various fireworks are generally attached to the container or box in which they are packed. They are fully discussed in Annex 14, Translation of the 1917 “Instruction on Liaison for Troops of all Arms, A. E. F.”
