Military Swarming
  • Definition Swarming occurs when the scheme of
    maneuver is a convergent attack of several
    semi-autonomous (or autonomous) units on a target
  • Basic characteristics
  • Attrition based - light swarm units avoid close
    combat
  • Attacks designed to disrupt cohesion of adversary
  • More fluid with common tactics being feigned
    withdrawal, ambush, feint, ruse, infiltration
  • Similar to double envelopment but not the same
  • sustained pulsing, not sustained close combat
  • Not a siege, involves maneuver

4
Difference Between Swarming and Guerrilla Tactics
  • Swarming
  • Several or more units
  • Sustainable pulsing
  • Dispersed, non-linear
  • Guerrilla tactics
  • Only a few units involved
  • 1 raid or ambush only
  • Dispersed, non-linear

5
What Can the Past Tell Us?
  • When did swarming work and when did it fail?
  • Are there any "dominant factors" which appear
    most frequently across many cases?
  • How do swarmers do against non-swarmers?
  • Does swarming work more frequently on offense
    rather than defense?
  • Does swarming success vary according to terrain?
  • How did swarmers satisfy their logistical
    requirements?

6
Historical Cases Completed
  • Scythians vs. Macedonians, Central Asian
    campaign, 329 - 327 BC
  • Parthians vs. Romans, Carrhae, 53 BC
  • Seljuk Turks vs. Byzantines, Manzikert, 1071
  • Seljuk Turks vs. Crusaders, Dorylaeum, 1097
  • Mongols vs. Eastern Europeans, Liegnitz, 1241
  • Woodland Indians vs. US Army, St. Clairs Defeat,
    1791
  • Napoleonic Corps vs. Austrians, Ulm Campaign,
    1805
  • Boers vs. British, Majuba Hill, 1881
  • U-boats vs. British convoys, Atlantic, 1939
    1945
  • Somalis vs. US Commandos, Mogadishu, 1993

7

Two Types of Tactical Swarming
Massed Swarm (Eurasian horse archers)
Dispersed Swarm (Somali Militia)
8
Example of Massed Swarming Arsuf, 1191
  • they are like tiresome flies which you can flap
    away for a moment, but which come back the
    instant you have stopped hitting at them
  • Classic Marching battle
  • Elusiveness based on Turkish horse archer
  • Excellent leaders on both sides
  • Conventional Crusader army adopts combined-arms
    box formation
  • Crusader cohesion never disrupted

9
Nomadic Swarmers from Central Asia
Sarmatians
Manchus
Mongols
Scythians
Huns
Avars
Parthians
Seljuk Turks
10
Example of Dispersed Swarming Mogadishu, 1993
  • Command and Control
  • Burning tires
  • Runners
  • Cell phones
  • Megaphones
  • Smoke from crash sites
  • Sound of firefights
  • Elusiveness based on
  • Urban terrain
  • Noncombatants
  • Home turf
  • Roadblocks, narrow alleys equalized mobility

11

Basic Pattern Analysis
Elusiveness (mobility or concealment)
Countermeasures negation
U-boat (1939-42) Seljuk Turks I
Woodland Indians Napoleonic Corps Somalis Boers
Seljuk Turks II
Mongols Scythians Parthians
Standoff firepower
Situational awareness
12
Conclusions from Preliminary Research
  • Feigned retreats and ambushes are common swarm
    tactics
  • Swarming strategy usually based on attrition
    knockout blows rare
  • Common problems are strongpoint reduction,
    fratricide
  • Logistics a constraint
  • Mongol toumens could not find enough forage in
    Germany or Syria
  • Terrain often key to elusiveness
  • Heavy woodlands, urban areas, ocean, grasslands

13
Modern Concerns
  • Dependence on reliable communications
  • Bandwidth concerns
  • Electromagnetic threats include EW, EMP
  • Terrain restrictions
  • Logistics swarming has never been done solely
    with ground vehicles?
  • Minefields
  • Unit morale

14
Why is Swarming Relevant?
  • Natural for future battlefield environment
  • Greater dispersion
  • Nonlinear
  • Command and control networked, decentralized
  • Small autonomous units operating independently
  • Greater reliance on aerospace firepower
  • Potential for medium rapid reaction forces who
    must
  • avoid direct fire battles
  • use standoff fires as much as possible
  • rely on elusiveness for survivability

Concluding Remarks
  • Given historical trends in dispersion, weapon
    lethality, and nonlinearity, swarming seems a
    natural fit
  • Potential operational concept for rapid reaction
    missions (Halt scenario)
  • Rapidly deployable joint forces will need to be
    elusive when halting heavy armor threats
  • Understanding swarming will also help to counter
    adversarial swarming

Linearity and Land Warfare
  • Linear armies conduct offensive operations on a
    continuous front in one direction at the
    tactical-operational level
  • Armies and tactical formations have become more
    linear in order to
  • Maximize combat power
  • Reduce their vulnerability to incoming missiles
  • Decrease fratricide
  • Ease command and control
  • Flank or avoid being flanked
  • In general, tactical deployment has evolved from
    dense phalanxes, maniples, and tercios to thinner
    and longer lines

25
Non-Linearity vs. Linearity
  • Non-linear warfare
  • Maneuver-based
  • Multi-directional fighting
  • No stable front, flanks, and rear
  • Units are dispersed and relatively more
    independent
  • Linear warfare
  • Attrition-based
  • Siege like
  • Methodical
  • Units heavier, slower, rely on stable supply

  • Swarming operations
  • Guerrilla and partisan operations
  • Airborne, airmobile, and special operations
  • 20th Century maneuver warfare - has introduced
    non-linear phases
  • Hutier tactics
  • Blitzkrieg
  • Soviet Deep Operation theory
  • Operational Maneuver Groups (OMGs)
  • AirLand Battle

Technology and Weapon Lethality
  • Impact of weapon technology usually only felt
    after a period of assimilation
  • Weapon lethality remained relatively flat
    throughout history
  • Artillery became the king of lethality in late
    19th century
  • Breech-loading, rifling, recoil-systems,
    smokeless powder, and high explosive shells
  • Technology of technology systematizes weapon
    development by the end of WW2
  • Air-delivered, precision guided munitions (PGMs)
    in the late 20th century rendered concentrations
    of vehicles vulnerable
  • Cluster, top-attack, self guiding IR, MW, GPS
    sensors

Quantifying Theoretical Lethality
  • If one assumes that lethality is the inherent
    capability of a given weapon to kill personnel or
    make material ineffective in one hour, where
    capability includes range, rate of fire,
    accuracy, radius of effects, and battlefield
    mobility, then quantitative measures can be
    computed to compare dissimilar weapons

History of Logistics
  • Roman legion required 1,000 pack animals for
    transport and 12.5 oxen, 120 sheep, or 38 pigs
    for food every day
  • Introduction of rapid firing small arms and
    artillery in the late 19th C. both increased
    demand and changed its nature
  • The Allies in one month of WW1 fired off 2x
    ammunition used by the North in the entire four
    years of the Civil War
  • Food, firewood, and fodder are 99 of supplies in
    1870, only 8 in 1940
  • Transportation technology has played major role
  • Baggage animal, surfaced roads, horse drawn cart,
    locomotive, motor truck, future tilt rotor?
  • The locomotive is the great logistical turning
    point
  • Allowed increase in size and mechanization of
    armies
  • Railways became bones of strategy
  • Motor trucks allow operational penetrations up to
    3-400 miles from railhead in WW2

The Armys Strategic Dilemma
  • Deployment of rapid reaction forces in the first
    several weeks of a crisis that is survivable
    against heavy force
  • Kosovo (1999) and the Persian Gulf War (1990) are
    two examples

Heavy forces not air deployable
No
389 C-130s
Yes
Light forces not survivable
0.10 tons
40 tons
70 tons
54
The Armys Answer Future Rapid Reaction Forces
  • Medium forces on the way
  • 20 tons or less
  • Transportable by C-130
  • Globally deployable 96 hours after wheels up
  • Interim force with LAVIII, MGS
  • Objective force with Future Combat System
  • Cannot face most enemy armor so we need new
    operational concepts
  • Army transformation motivated in part by what we
    think future war will be like

Our Problem How Do Medium Forces Fight?
  • To survive and be effective, rapid reaction
    medium units must
  • avoid direct fire battles
  • use standoff fires as much as possible
  • rely on elusiveness for survivability
  • But The Army does not have the operational
    concept to do this

How do these?
fight these??
Spam in a can?
56
The Need for Rapid Reaction Force
  • Halt the enemy when he invades allied territory
  • Other time sensitive missions like stopping
    ethnic cleansing
  • Counter enemy anti-access strategies (airland
    inside)
  • Deter aggression

57
Related Research in Enhancing Rapid Reaction
Forces
  • Arroyo Center high level simulation has focused
    on enhancing air-deployable forces so they can
    defeat enemy mechanized forces
  • Defensive posture
  • Tried making light forces lighter or heavier,
    introduced medium force
  • Combination of remote indirect systems and
    organic fire works best
  • Project Air Force (PAF) - seeking ways to enhance
    air powers ability to engage elusive ground
    targets
  • Enhancing Aerospace Operations Against Elusive
    Ground Targets (2001)

58
The Solution Must Be Joint
  • The future environment and the nature of medium
    forces calls for a joint solution
  • Medium ground forces needs airpower to provide
    the offensive punch (the hammer)
  • Air forces need a maneuverable ground element to
    act
  • As the anvil to flush out elusive targets and
    force them to mass or move
  • As forward air controllers

59
Dissertation Objective
  • Outline operational concepts based on swarming
    for two scenarios
  • Initial halt campaign a light/medium ground
    force uses swarming to stop enemy mechanized
    forces
  • Dispersed operations a light/medium ground force
    uses swarming against adaptive enemies who have
    dispersed

60
Methodology
  1. Complete historical research add 30-50 more
    historical cases to a database and examine them
    for patterns and insights
  2. Model dispersed nonlinear operations
  3. Combine insights and provide a framework for two
    operational concepts based on swarming

61
I. Qualitative Methods
  • Gather data on 40 cases
  • Identify dominant factors and constraints
  • Draw inferences, eliminate hypotheses,
    pattern-match, make analytic generalizations
  • Use the Qualitative Comparative Method (by
    Charles Ragin)
  • Place binary data in truth tables and build a
    boolean equation

62
II. Modeling
  • Most models tend to emphasize attrition warfare
    and linear operations along well-defined front
    lines (based on Lanchester equations)
  • EINSTein is a simple agent-based model that
    assumes land combat is a complex adaptive system
  • Highlights SOPs and contingency plans when units
    lose situational awareness
  • Allows tradeoffs between centralized and
    decentralized command and control structures
  • Models network verse network conflicts when units
    are autonomous (more applicable to 2nd scenario)
  • Explore swarming tactics (like creating a golden
    bridge, feigned withdrawals, the half moon)

63
III. Create Operational Concepts
  • Combine data and insights from earlier phases
  • Formulate hypotheses, establish parameter values
    from qualitative data for input to computer
    simulations
  • Considering tradeoffs in
  • Schemes of maneuver
  • Tactics, formations
  • Command, control, and communications
  • Behavioral rules, SOPs
  • Sensor and weapon range
  • Coordination of aerospace and ground elements
  • Constraints (terrain, mission)
  • Address concerns such as destruction in detail,
    fratricide, unit cohesion, dependence on
    communications, logistics, minefields
