Currently there are 2 types/models of battle noise simulators in use with the Australian army, list them by name and model number.
F2A1 Battlefield Grenade
F3A1 Projectile Groundburst
What is the purpose of battle noise simulators?
To provide battle noises and simulate the effects of grenades, artillery and mortar fire
Flare surface trip A301 comprises of three assemblies, one of them being the fuze assembly, list the other two.
Illuminant assembly
Mounting bracket assembly
Describe the complete functioning of the flare surface trip A301 when set up for pull pin operation.
- Flare activated by release of safety lever.
- Striker mech impacts percussion primer.
- Primer initiates ignition transfer composition.
- Composition ignites flare priming composition.
- Fuze assembly ejected and flare burns.
What is the light intensity of the sig distress d/n No1 Mk5
5000 candlepower
What is the duration of smoke emission from the sig distress d/n No1 MK5
17-25 seconds
Sig kit distress ships life boat Mk3 has the following items
- – x Signal — handflare mk7 (—–)
- – x signal life smoke mk3 —- (—–) and
- – x signal parachute — rocket mk3 (—-)
6 red handflare

Simulator EOD L1A1 contains 32 grams of what composition.
Comp SP302
List the main components of the BESS system (3)
Coded radio transmitter
Receivers
Pyrotechnics
The flare aircraft LUU 2a/b comprises of four main assemblies, one of them being the case, list the other 3.
Timer assembly
Parachute assembly
Igniter assembly
What is the light intensity of the candle of the flare aircraft LUU2 when functioned
2 million candle power
Describe the functioning of the marker location marine Mk 58 mod 1 from the activation phase.
- sea water enters the battery cavity hole and serves as an electrolyte to activate the mk 72 battery.
- the current from the battery initiates the Mk13 squib which ignites the starter mix of the first pyrotechnic candle
- the starter mix, inturn ignites a transfer time fuse which carries the ignition to the second candle starter mix which ignites the final burning.
- each candle burns for a minimum of 20 minutes.
The marker marine Mk AN25 Mod 3 is to have a warning notice, what is it?
Do not handle contains phosphorous, May cause serious burns, notify police or military.
What is the total smoke / flame emission time of the marker marine location Mk58 mod 1?
40-55 minutes
The sig illum M126A1 emits what colour star function.
Red
Signals M125A1, M126A1 and M127A1 comprise of three major components. What are they.
Rocket barrel
Rocket
Signal composition.
How much candle power does the Sig illum M127A1 emit?
125,000 candlepower
Projectiles fall into two main groups, one is solid projectiles, what is the other.
Filled projectiles.
Integral anvil (berdan) is one type of ignition system used in SAA, list two others.
Separate anvil (boxer)
Rimfire
What are two methods of securing percussion primers to cart cases.
Push fit
Ringing
Punch stabbing
SAA usually consist of four main components, what are they.
Projectile
Cart case
primer
Propellant
What is one of the base marking symbols on SAA
Manufactures symbol
Year of manufacture
Calibre
Model number
What are the two grades of CART 12.7mm MP NM140 Raufoss and what is the difference between them.
Grade A and grade b
Grade A - manufactured to a higher tolerance
Explain the operation of the 12.7mm MP NM140 Raufoss from impact.
- nose of the projectile in compressed and the incendiary is ignited.
- the projectile passes through the target and the pressure continues to increase and the incendiary composition ignites the high explosive
- the increase in pressure then burns to detonation the High explosive producing blast fragments.
- the secondary incendiary charge is ignited and burns for 1 second.

Focus on main areas
How much noise does the F2A1 simulator make
120 - 140DB
What is the whistle burn time for the F3A1 simulator
3-6 seconds
Describe the functioning of the LUU 2a/b from release to descent.
- time knob pulled and is activated
- clock imitates release mech, which ejects timer assembly from case.
- timer attached to parachute and chute is deployed.
- chute applies a load to ignition lanyard which activates flare ignition system.
- ignition system ignites candle.
- aluminium case consumed
- during candle burnout explosive bolt cuts one chute cable which collapses chute and sends it plummeting rapidly towards the ground.
Safety precautions for BESS
Static EMR
