IR Illumintatin 1000m 60sec

Question 10

Point Detonating Fuze

Answer 10

functions on impact
can be used with HE and WP projectiles
Is commonly referred to as “quick” and PD

Question 11

Delay Fuze

Answer 11

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

Question 12

Proximity/Near Surface Burst (NSB) Fuze

Answer 12

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
