To reiterate the basic chain structure of power:

strength < skill < tactics < strategy < logistics < politics

Morale is a real if intangible thing; high morale will increase effectiveness (to a finite limit), low morale will decrease effectiveness (to a finite but negative limit).

There are five basic inputs that affect morale:

• food, drink, and intoxicants
• sex
• lodging
• rest and recreation
• a sense of superiority

A wise leader will ensure these factors are provided regularly and at as high quality as practical.

If any are unprovided, forces will tend to autonomously scrounge them from fellows or extract them from surroundings. This sourcing will generally reduce logistic burden but increase political burden.
