For information on the units and army see: units
Soldiers are the POP type, which represent the fighting men of a nation. They are used for raising armies, with 3000 soldiers being used in each brigade. However, only 1000 soldiers are needed to create the first brigade from a province. Soldiers are also used for reinforcing damaged brigades, and the soldier POP will take damage when men are killed in action. The amount of people lost can be reduced via the nation's "military hospitals" level, which can be increased by researching certain technologies and obtaining certain inventions. Brigades have the potential to revolt, and will do so whenever the POP they stem from does.
Like officers they're paid directly from the military spending slider, so if spending is too low they won't meet their needs and demote, while if spending is high promotion to the POP-type will be increased.

Promotion and demotion
The following factors affect the likelihood of a Soldier pop choosing to change jobs to a particular pop type.
|Literacy is less than 30%||−1%|
|Province has more than 0.2% officers||−100%|
|Literacy is at least 50%||5%|
|Military spending slider is at least:||30%||5%|

|Literacy is less than 20%||−2%|
|Literacy is at least:||30%||1%|
|State has factories||10%|
|State has no factories and
the country can't build factories
|No work available locally for Craftsmen||−100%|
- There is a third unemployment condition, that the state has factories and farmer unemployment is less than 10%. This is probably a bug and should check craftsmen unemployment instead.
- Unknown what this means. Possibly "doesn't have a core of a country of this pop's culture group".
- These factors are added together before being applied.
