Corps,Division and brigade.

[_Cambronne_]

As I understood from the manual a Corps is composed by several units.But when we have an army with 2 Corps each corp having 2 Divisions with 2 brigades with 2 regiments,how many corps do we have? Only 2 corps that are under CinC's orders? or do we have 8 corps(the brigades with 2 units under each of them)?

[Montecuccoli]

I think you are messing something 

Army is composed by Corps, Corps are composed by regiments, regiments are composed by battalions or squadrons.

Divisions is another name for Corps as it is Column...

anyway, in small battles (rear guard mode), is possible that Army is called Corp.. and so the Corp below changes its name in "division"

[Gunfreak]

Actualy historic wise, all corps had divisions(except for Prussians in the 1813-1815 period.

But not all armies had corps.

In the 1805-1806 period only the french used corps which gave them an advantage over the rest.

For instances

The 3rd corps had 3 divisions, each division had two brigades each brigade had 2 regiment and each regiment had two battalions.

While the Prussiasn had sevral loose divisions in the army with no corps,

The hierarchy is from top to bottom :

Army : composed by several corps (max 11 in LG)
Corp : composed by several divisions (in general, less than 6)
Division : composed by several brigades (in general less than 4)
Brigade : composed by several regiments (in general less than 4)
Regiment : composed by several battalion (in general less than 6) or squadrons (for cavalry) or companies (for artillery)

In LG the word "unit" is used for infantry and cavalry regiments and artillery companies. It is the smallest unit in the game (battalions and squadrons cannot be separated from their regiment).

So to answer your question, the CiC will have 2 corps under is command.

[_Cambronne_]

so,when I give the order to a corp commander to organize the units in double line and the corp in mass order,the regiments will be deployed in double line.But will the divisions and brigades within the Corps be organized in double line or massed?

[CBR]

From what I can understand in the manual, a player controlling a corps (in a 4v4 MP game) will have to give orders to individual regiments because brigade/division AI is not in this version of the game right?

book 2, p5

However, certain intermediary levels in the hierarchy, such as the division or brigade, can be
ignored (they’re not really a major part of this version of the game. But two additional
AI’s will come into force according to the envisaged outcomes)

[Ras]

There are two AI's the Regimental AI and the Group AI.
You can give orders directly to the Regiments when you choose the Colonel's menu, but you don't have to.
From the manual:

The Group AI (to avoid making the text cumbersome, we’ll from now on refer to the
Army Corps AI, though a group may also refer to a Division, a Brigade or even a
Regiment) receives orders from the top brass and then organises the Group units so
as to carry them out.

There are 4 formations for corps : battle, echelon right in front or left in front, chessboard. The only case a corp is form in 3 lines deep is in chessboard formation. For the other formation, it depends on the % of reserve you chose.

If you organize a corp composed by 17 units (regiments or arty cies) in battle fomation, for example and you decide to have a reserve of 50% : there will be 9 units in first line and 8 in second. If you don't want any units in reserve, there will be 17 units in first line and for 30% there will be 12 in first line and 5 in second.

Columns, line, mixed order are units formations (régiments).

So you have to define corps formations (battle, echelon or chessboard) and units formations (column, line, mixed order).

[LNDavout]

all will be clear if we start playing

[Darsh]

Corps represent the corps/divisions/brigades
Units represent the regiments

[_Cambronne_]

ok all is more clear now,thanks!

[Vorontsov]

In other words, we'll have in LG more primitive XVIIIc hierarchy (corps-regiments) than napoleonic (corps-divisions-brigades-regiments).
 Little disappointment for me

[Gambrinus Glubbe]

It saws above that the Group AI can be Army, corps, division or bridage-level.

Because the AI for the Napoleonic hierarchy will be added later.

Corp isn't a 18th century organization but a Napoleonic one  .

LG organises armies in corps, divisions, brigades and regiments. But only corps and regiments have an AI.
