MYP Individuals & Societies Military Drivers Notes

What Are Military Drivers?

1. Military power rarely depends on battlefield skill alone.
2. Empires rise, expand, and survive when they solve practical military problems:
   1. how to recruit and organize fighters, how to supply them, how to move them quickly, how to maintain control over conquered populations, and how to combine strength with others when necessary.
   2. These underlying factors are military drivers, the conditions and systems that make sustained military success possible.

How Do Military Drivers Explain How Empires Turn Force Into Control?

1. A useful way to think about military drivers is to separate winning battles from winning empires.
   1. Winning battles requires tactics, leadership, morale, and sometimes luck.
   2. Winning empires requires systems that keep armies ready, supplied, and politically effective over long distances and long time periods
2. A military driver is powerful when it improves one or more of the following:
   1. Speed (moving troops, messages, and supplies faster)
   2. Force Concentration (bringing enough soldiers to the right place)
   3. Sustainability (keeping armies active for years, not weeks)
   4. Internal Control (policing territory and preventing rebellion)

Why Do Standing Armies Increase Readiness, Stability, And Imperial Reach?

1. A standing army changes the basic timing of war.
2. Instead of raising troops only when a threat appears, the state maintains trained forces that can respond immediately.
3. This matters most for empires with many borders, many provinces, and frequent internal security challenges.

Case study

Rome: Professional Service, Standard Organization, And Border Security

• Rome developed a standing army system in 108 BCE.
  • Under this system, male citizens under 45 were eligible for service, and equipment was provided by the government.
  • Soldiers could serve full time for up to 25 years, earning a regular wage.
• A key driver here is not only the size of the force, but its standardized organization:
  • A legion was about 5,000 (including soldiers and support staff)
  • Legions were divided into cohorts (about 500) and centuries (about 100)
  • Each legion was commanded by a general, often responsible to a provincial governor
• At its peak, Rome had about 450,000 soldiers across 33 legions. These forces were distributed across the empire to defend provinces and also to act as a police force.
• Rome also rewarded veterans with farm land after service. Importantly, this land was often near borders, which meant:
  • Veterans could be recalled in emergencies
  • Border regions became more culturally "Roman" over time (through settlement and local influence)
