ABSTRACT:
A firing train function indicator 10 for a self neutralizing recoverable land mine 16. An explosive bolt 20 is used to hold a helical spring 44 in a compressed state. The upper portion 30 of the bolt 20 is attached to one end of the spring 44 and the other end 32 of the explosive bolt 20 is attached to base 38 of indicator 10. A highly visible inverted cup-shaped flag 48 is also attached to the upper portion 30 of the explosive bolt 20. The detonator 18 of the explosive bolt 20 is fired when the mine 16 self neutralizes to separate the upper portion 30 of the bolt 20 from its lower portion 32. The spring 44 is then free to expand raising the flag 48 above the self neutralized mine 16. A flag 48 so deployed, identifies the location of a self neutralized mine 16 and is a reliable indicator to recovery personnel that the mine 16 is in fact safe to approach and recover.
