EDIT: This is a draft, for now.
This is a very summary about what the units are made about. It's good for RUS, but should be almost the same for other games. You can find more in [url]http://www.ageod.net/agewiki/Category efinitions[/url]
1) Players move groups /forces /stacks, of units
(figures to be moved on the map). These forces can be
independant, or
often Corps, and
sometimes Armies (which command Corps).
2) In these groups, players put units
(counters to be moved in the bottom of screen; on the map they are not directly moved by the player).
. These units are usually 'basic units' (brigade scale),
. but the player can sometimes, using them, create a 'composed unit' (division scale)
(a very unit made of some basic units).
. The player can create new basic-units, by using the reinforcement system;
the game can create some, planned by the scenario.
When a unit is detached out from groups, it creates itself its new own group.
3) The elements /sub-units (regiment scale) compose the basic units (and so the composed ones).
The elements can not be (directly) moved by the player (but can be checked in their panel).
3bis) The player can (only) buy chits (regiment scale), which go in his replacement pool.
He can create an element (for a unit missing a destroyed element)
by asking one chit of its type from the replacement pool.
These replacement chits come with full strenght.
I'm less confident for the following points:
4) The ?strenght points /conscripts companies (company scale)? compose the elements and the chits.
which then go in his ?replacement/conscripts? pool. (companies from conscript pool go in replacement pool??)
The game gives back, gratis in this pool, some companies immediatly from the losses (battle/attrition).
5) The strenght-points (platoon scale?), in the elements,
are lost by the damage values of the attacking elements for each hit they succeed.
The replacement system randomly gives back, to the elected damaged elements,
some strenght-points from the chits in the pool
(this is not directly the chits which are spent by this system, but first their strenght-points).
6) Number of men
