Weapon Systems:
Combination of a
weapon and the
equipment used to
bring the destructive
power of the weapon
against the enemy.
Weapon Nomenclature &
Identification
AN/SQS-53 Sonar
“AN” means the nomenclature complies with the system
jointly adopted by U.S. armed forces (Army- Navy).
First “S” identifies installation type
– ...“water surface craft.”
“Q” identifies equipment type
– Sonar and underwater sound
Final “S” indicates purpose
– Detection and ranging.
53 is the model number.
Letter “D” indicates the version.
Weapon System Components
Radar - Detect, locate, and identify the
target
Tracking System - Direct or aim a delivery
unit
Launching System - Deliver weapon to
target
Missile/Warhead - Destroy target when in
contact with or near it
Weapon System Requirements
Reliability
Flexibility
Safety
Simplicity of Operation
Maintainability
Specific Military Specifications
Law of Armed Combat (LOAC)
Geneva Conventions
– rules limiting the barbarity of war
– protect people who do not take part in the fighting
First Geneva Convention 1864: Care of
wounded soldiers
In 1949 Conventions were revised and
expanded:
–
–
–
–
Convention I: Wounded and sick
Convention II: Wounded and shipwrecked at sea
Convention III: Prisoners of War
Convention IV: Civilians under enemy control
LOAC
Combatant
– A combatant is any member of the armed
forces, man or woman, except medical and
religious personnel.
– in combat they are quite clearly armed and do
not attempt to disguise their military
intentions.
Rules of Engagement
Not the same for every situation
Key Principles
Military Necessity
– Accomplish legitimate military objectives
Distinction
– Discriminating between lawful combatant
targets and noncombatant targets
Proportionality
– Restricts degree of force to that needed to
accomplish the military objective
Courts Martial and Law of War
Military members who violate LOAC are
subject to criminal prosecution and
punishment
General Courts-martial have power to try
certain persons for violations of the law of
war
– “But I was only following orders”
– No statute of limitations on war crimes
LOAC Rules
AN INDIVIDUAL SAILOR REMAINS
RESPONSIBLE FOR HIS OR HER
ACTIONS AND IS EXPECTED TO
COMPLY WITH THE LOAC
