Point Detonating Fuze
functions on impact
can be used with HE and WP projectiles
Is commonly referred to as “quick” and PD
Delay Fuze
Functins .05 sec after impact can be used with HE projectiles HE delay is effective against -earth and log fortifications -some masonry and concrete targets -personnel in light frame structures -lightly covered emplacements -dense woods Not effective against heavy -armor, masonry, concret
Proximity/Near Surface Burst (NSB) Fuze
is radio activated
functions when it receives the reflection of a self- tranmitted radio signal
Has height of burst 0-3ft NSB or 3-13 Proximity
HE Prox/NSB is useful in situations where an airburst is desired without the need to adjust the height of burst
Light foliage has little effect, but heavy foliage will cause detonation
Is particularly effective against:
-Personnel in any disposition without overhead cover
-Lightly skinned vehicles
Time Fuze
Used for illumination and WP
