Companies (group of players) are the result of the regrouping of sections, a section representing a player.
The sections of a company have a rank (Major, Sergeant-Chief, Sergeant, etc.) within the company. This rank is visible in the Center Control, depends on the level of the company and, on the other hand, is independent of the level of the section.
A company allows to make gifts (of units and W$) free of any charge between members of the same company and to reach special units and actions (camp, air raid, parachuting of unit, hospital...)
The level of a company depends on the mean level of its chiefs and the sections grouped within it. The more the level of the company increases, the more it is difficult to increase it.
The level of the company determines the number of chiefs and members who are grouped in it (except for the trainees).
Important remark: the level of the company increases as it is the commander who makes the action (transitivity: the level of the section increases as it is the commander who makes the action, and the level of a company depends on the mean level of its chiefs and the sections grouped).
