Use: The flare indicates, to cooperating air elements, a line of position or direction. It is also used for troop-recognition purposes. |
|
Description: The flare consists of a paper cylinder containing a pyrotechnic compo-sition. It has a wooden base block with a 20-penny spike through it, and a match head covered by a removable metal cap, under which lies a wooden disc. A plastic film seals the metal cup to the flare body. The outer head of the wooden disc has the scratching surface required to ignite the match composition. |
|
Operation: The flare is stuck in the ground with the spike as a support. The plastic seal is pulled off and the wooden disc scratched against the match composition, which ignites the flare. |
|
Remarks: These ground flares are not procured by the Navy at present. |
