Q
What are the main characteristics of Thermobaric rounds.
A
Updated form of FAE round.

24
What are the 3 types of fuzes?
Point detonating
Base detonating
Point initiating base detonating
25
Where is the fuze located in point detonating round?
In the nose.

26
Where is the fuse located in a base detonating round?
In the base of the round explosive composition.
| Firing pin strikes hammer and then explosive train begins.
27
How does the fuze operate in a point initiating base detonating round?
Upon impact, one piezo crystal inside the nose is crushed, generating about 12-50 V that excites the solenoid, causing it to release the firing pin to initiate the explosive train.
