The gun
What are the 3 types of muzzle break?
Built up
Solid forging
Swaged- single or double baffle
What are the 2 categories or breech mechanisms
Screw
Sliding
What do fume extractors aid in?
They prevent the fumes entering the crew compartment
What are the methods or barrel construction?
Wire wound Built up barrels loose barrel Composite barrel Monobloc
What is the function of ordnance?
It provides a vessel to contain the force of the burning charge in a way that the energy produced is transmitted safely and predictably to the projectile and it imparts direction and stability to the projectile.
What is a carriage?
Ordnance that is transported on its wheels and is fired with its wheels in contact with the ground.
What is a mount?
It is ordnance that does not fire with its wheels in contact with the ground.
What are the 2 types of mounts?
Mobile
Self propelled
What makes up the super structure?
Saddle Recoil system Cradle Balancing gear Elevating gears Traversing gears Sights
What are the 3 types of cradle?
Trough
Open
Ring
What makes up the recoil system in a piece of ordnance?

Rapson nut and screw
What makes up the basic structure?
Platforms Aarticulations Spades Trails Wheels and axles Saddle supports Suspension and brakes
What are the 4 types of trail?
Pole
Box
Bowed
Split
What are the main components of the mortar bomb?
Bomb body including fuze
Tail unit
What are the two types of augmenting charges?
Thin leaves of plasticised and bonded propellant stapled together.
Hollow plastic cartridges containing granular propellant
What is the definition of a mortar?
A weapon where the main recoil force is transmitted directly into the ground through the base plate. Usually smooth bore, muzzle loaded, fin stabilized, with its own propelling charge at low Muzzle Velocity and high trajectory.
What are the types of artillery ammunition?
HE Smoke Illuminating Guided projectile Submunitions
What are the 5 basic requirements of artillery?
Range Accuracy and consistency Mobility Protection Ammunition
What are the 2 main methods used without altering the artillery weapon system to increase range?
Ballistic coefficiency
Post firing boost
Define the world accuracy
The measurement of precision where the MPI of a group of rounds can be placed on the target
What is the definition of ammunition?
All of the material used in discharging all types of fire arms or any weapon that throws projectiles, shot, shrapnel, bullets, cartridges and the means of igniting and exploding them as primers and fuzes. Chemicals, bombs, grenades, mines and pyrotechnics are also ammunition.
