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.

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.
