What are the 7 main points of ammunition care and preservation?
- Provide adequate ventilation
- Protect from direct sunlight

One of you gunners attempts to fit an M577 Fuze onto an HE projectile. Explain why this cannot be done?
It is an igniferous Fuze used on carrier projectiles. It doesn’t have a booster and would be a dud.
What is the type of primer used with the M777?
M82
What is the purpose of the booster on a disruptive Fuze?
A necessary unit with an HE projectile, it amplifies the shock wave enough to detonate the HE bursting charge.
What are the types of granulation for the following propelling charges
(Green bag) M3 - single perforated
(White bag) M4 - multi perforated
(Mac Low) M231 - single perforated
(Mac High) M232A1 - triple perforated
(Red Bag) M119A2 - multi perforated
What are the types of fuzes and what actions do they produce?
Igniferous - produces a spark or spit of flame to ignite the expelling charge in a carrier projectile.
Disruptive - produces a detonation to detonate a bursting charge of an HE or WP projectile
What are the reasons for painting ammunition?
Prevent rust
Ease of identification
Camouflage
What are the current 155mm projectiles in service today?
- HE M107 and M795
- Smoke DM45
- Illumination M485
- RAP M549
- Excalibur M982
List the components of a propelling charge?
Primer
Igniter
Propellant
With the C32 Fuze, what is the difference in functioning between a Fuze that is set to proximity MANUALLY and INDUCTIVELY?
MANUALLY - when the Fuze reaches 7sec of flight, the proximity sensor starts target detection.
INDUCTIVELY - 2 seconds before the programmed Fuze setting is reached, the proximity sensor starts target detection.
What is the standard weight square zone for 155mm HE?
4 squares
What is the definition of an artillery Fuze?
It is a device used with a projectile to cause it to function at the time and circumstances required.
Label the exterior parts of the HE projectiles?
- Ogive
- Shoulder
- Bourelet
- Body
- Driving band
- Base
- Base plate
Name the methods used to mark ammunition?
Stencilling
Stamping
Label and tags
Colour coding
Define an explosive?
A substance which when suitably ignited is capable of exerting a sudden and intense pressure on its surroundings
