Less Than Lethal Weapons Requirements for
Military Forces
2
OVERVIEW

• The Situation
• The Requirement
• Terms of Reference
• Technology
• - Guns
• - Ammo
• Target Vulnerability
• Tactical Application

3
The Situation

• The Fluid Battle Environment
• Organized Military Opposition
• Unconventional Warfare
• Civil Unrest
• Non Combatant Screens
• Dynamic Rules of Engagement
• Currently Limited Response Options
• Water Cannons
• Sponge Balls
• Rubber Bullets
• Etc.

4
The Requirement

• A Multi Purpose Weapon with Scaleable Lethality
• Near instant Scalability from Lethal to Non
  Lethal and Back
• Readily Deployed
• Minimum Logistical Tail
• Potential for various ammo types ABM,HE,APDS

5
NATO Policy Less Than Lethal Weapons (LTLW)

• Incapacitate or repel personnel, with a low
  probability of fatality
• Expand the range of options available to NATO
  Military Authorities.
• LTLW shall not be required to have zero
  probability of causing fatalities or permanent
  injuries.

6
Design Elements of a Scaleable Kinetic Energy
Weapon

• Predictable delivery of subprojectiles requires
• MV Correction - Minimize error in range
• Accurate Fuzing - Precise distance from the
  target
• Uniformity of the payload - Subprojectiles same
  size
• Uniformity of payload distribution - area
  coverage

35mm Air Burst Munition Kinetic Energy Time Fuze
(ABM-KETF) Layout
Note The payload (500g) is composed of
cylindrical W-Subprojectiles (here 3.3 g). For
engagements other than AA (e.g. G-to-G) the mass
of the subprojectiles can be reduced accordingly
(e.g. 1 to 1.5 g)

Ahead Payload Growth Potential

• Traditional Payload Effects
• Mechanical effects based on KE (Frags /
  Subprojectiles)
• Flash Bang
• Emerging Payload Effects
• Disabling passive effects (against target
  sensors) Chaff, Phosphor, ...
• EM waves effects (against target electronic
  system) NNEMP Non-Nuclear EMP, HPM Hyper Power
  Microwave, UWB Ultra Wide Band, ... in
  directional radiation pattern

Summary

• Military gun systems can extend their mission
  capabilities from lethal through near lethal to
  less-than-lethal. 
• Demonstrated technology exists that can be
  applied in the development of direct fire weapons
  systems.
• The vulnerability of a broad range of targets can
  be accommodated within the mission profile.
