(In Commandos: Behind Enemy Lines)
Ranks are the positions in the hierarchy of the game that you can be throughout the game based on a merit-based rating system.
These are the ranks (6 Mission Merit needed to get promoted)

Merit screen at the end of each mission
- Lance-Corporal
- Corporal
- Sergeant
- Quartermaster
- Lieutenant
- Captain
- Major
- Colonel
- Brigadier
- General
- Field-Marshal
You can earn a maximum of 3 Mission Merit per mission.
There are two categories, granting 3 Merit each, evaluated at the end of every mission:
- Mission Time: Time it takes to complete the mission.
- Sustained Damage: Damage your commmandos take during the mission
This two parametres will be used to calculate the final Mission Merit you'll earn:
Mission Merit = Floor[ (Mission Time + Sustained Damage) / 2 ]
In other words it will get the average result from both categories and remove the decimal part.
This Mission Merit will be added to the overall Merit of the player.
