Thank you Ralb! I did watch some of his videos but I missed the one about the toolbar apparently.
Hey Camrik, just because some of my videos can end up being somewhat longwinded, especially the Grog Toolbar series, which I largely did on the fly and off the top of my head, Il try and summarize some of the more pertinent aspects as they relate to your questions here.
Generally speaking Infantry formations for the Grog toolbar can be grouped into 4 categories.
They are.
1.Melee formations
2.Firing formations
3.Cavalry defense formations
4.Movement/marching formations.
With regard to your first question about the various column by division formations, all of these can be considered melee formations. Units in Column by Division(sometimes also referred to as the "assault column") receive a bonus to their melee attacks when attacking enemy infantry that is not also in the assault column formation, like Line for instance(I believe the bonus is something like 15%)
Infantry in column by division can only charge. They cannot fire while in column by division. In order to fire the unit will first take a line formation, and then fire. This will happen automatically if a unit in column by division moves within engage distance of an enemy unit and either you, or the AI does not continue to close with the enemy unit and engage in a melee.
As to what version of column by division is best for what situation, Il be honest, Ive been playing this game for 4 years, and Ive never used anything but the close order formation(the most compact formation)
This is because the point of the assault column was to use a dense block of troops to punch through the enemy's thin line formation, and through brute force break it up.
In the same way you wouldn't throw a punch with your fist only half closed because you can generate much more concentrated power at the point of impact with a fully closed fist, the close order column by division should theoretically have the same effect.
I say theoretically because Ive never actually bothered to see if the half and fully open formations have any different effects with regard to melee compared with the close order formation. They could all be the same and its simply a visual difference between the three. Or they could be different, but logically, if they are different, I cannot see a reason why the half and open order formations would have more striking power than the close order version. That just wouldn't make sense. The close order, being the denser of all three versions, should be the strongest.
So I just always use the close order formation. By all means feel free to experiment with it though.
Line formations are the opposite of column by division. While column by division formations are designed to maximize striking power with the bayonet, line formations are about firepower. The line formation is designed to bring all available muskets to the front lines in order to achieve maximum firepower. So rather than a dense block of troops, the line formation dispenses with depth and goes with length.
For Line formations, its real simple, and it all just has to do with the sequence of events. By default, the Grog Toolbar will move units using the Column by division formation.
There are three main Line formations
1. Line
2. Line Hold Form
3. Combat Line
Combat Line is an automatic formation that will happen once the unit actually engages in fire combat with an enemy unit. Its simply a reshuffling of the standard 2 rank line to a 3 rank firing line. Its happens automatically so you really never need to worry about this formation.
Regular line and Line Hold Form end in exactly the same formation. The only difference is how they move to the destination.
If you move a unit and select Line, the unit will move to the location in the column by division formation, and then deploy into line.
If you move a unit and select Line hold form, the unit will form line, or if already in line, will hold that formation and then move to the location you set for them. Line Hold Form is short for Line Hold Formation, so what it does is kind of in the name of the formation itself. You're moving the unit while holding the line formation.
In either instance, if the location you move your unit to is within firing range of an enemy unit, the game will automatically go one step further and deploy the unit into combat line and begin firing.
