What are key characteristics of HE rounds?
Mainly anti-personnel or for engaging soft skinned vehicles.
Lack capability to penetrate modern armor.
What are the main characteristics of FAE rounds?
Designed to destroy light vehicles and combat field fortifications.
The explosive warhead is composed of a highly volatile fuel that will bond with oxygen particles in the air, saturating a small space.
Requires atmospheric Oxygen.
VERY LITTLE FRAGMENTATION.
What are the main characteristics of HEAT rounds?
True anti armor threat.
Designed under MONROE Effect of directional charges.
Highly lethal JET torch that penetrates steel (temp well over 2750 F, 1500 C).
What are the main characteristics of HESH rounds?
Functions under sledge hammer principle.
Steel nose impact debilitates and crushes armor, causing chipping from inside.
NOT Anti-armor.
What are the main characteristics of Tandem rounds?
Counter ERA protection.
The precursor charge penetrates or detonates the ERA block, then the primary shaped charge will follow through and penetrate the base armor.
What does ERA stand for?
Explosion Reactive Armor
What are the main characteristics of Thermobaric rounds.
Updated form of FAE round.
Differs from the FAE in that it consists of a fuel rich in mono propellant and energetic particles (ie, powdered fluorinated aluminum).
Explosion results in intense fireball with high blast over pressure.
What are the 3 types of fuzes?
Point detonating
Base detonating
Point initiating base detonating
Where is the fuze located in point detonating round?
In the nose.
Can be an impact type or time fuse.
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.
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.
What does MACLOS stand for?
MAnual Command Line Of Sight
What does SACLOS stand for?
Semi Automatic Command Line Of Sight
What does ACLOS stand for?
Automatic Command Line Of Sight
