Chapter 1

Basic Definitions Weapons: Instruments of offensive or defensive combat...something to fight with.

Basic Definitions Ordnance: Military supplies including weapons, ammunition, tools, & equipment.

Basic Definitions 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 ReliabilityFlexibilitySafety 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
