CRT - Simple explanation if you want to modify it

[KaRei]

Were you interested how are battles calculated in Eu2? Did you want to modify battle stats, but you didn't understand battle calculations from FAQ?

This is simple graphical explanation of a battle calculations.
You can easily see here from where is game taking the values and where they are then used.
Tell me if it's incorrect.
Only morale calculations are missing, can somebody help me?

Tutorial of battle modifications ...

CRT.csv file

We can say that CRT table is a table of "damage levels". Column A could be the strongest level and column E could be the weakest level. This is good to keep an order in the file.

What I'm calling damage level? I'll explain it on an example:
Let have three soldiers. One of them is in plate armour, the second has only a T-Shirt, and the third has a sword and will attack them. He will surely make less damage to the man in armour, and make higher damage to the brave "idiot" in T-Shirt.
So against the armour the soldier will use lower damage level (column E for example) than against the T-Shirt (column A).

Each line in the column is representing abilities (and luck) of the attacker.
Say, the soldier with sword is unexperienced and in his bad luck the man in T-Shirt will jump aside in front of the sword, so the soldier won't hit the man (although he is still using column A, he's now using the first line of the column).
On the otherside takes the sword a swordmaster and make a direct hit (he is also using column A, but now he's taking line 16).

In each column are two numbers. The first one is casualties moddifier and the second one is morale moddifier. (On the picture are these two numbers swapped (I'll correct it sometime)).
By increasing the morale modifier (2nd, 4th, 6th, ... number in line in the CRT file) you will make the morale dropping down faster during the battles. I was trying to increase it 10x. Each battle then took only one or two days, because morale was down almost immediately. On the other side I reduced it 10x and the soldiers were fighting then until their death and none of the battles ended by morale loss.
By increasing the casualties modifier (1st, 3rd, 5th, ... number in line in the CRT file) you will make the soldiers dieing quicklier. Increasing it 10x could make the battles short, but destructive (20k army can die during few days). On the other side reduce it 10x will make the soldiers almost immortal.

So this was CRT. By modifiyng it you can change the duration of battles, balance between importance of Morale/Casualties, and how different will be power used against different tech levels.

Landfire/Landshock/etc .csv file

Most of things were said in above, so this will be short. Landfire/Landshock/Navyfire/etc. are files that has a table defining which damage level (column from CRT file) will be used by soldiers of one tech level against another. On the left side of the table are tech levels of soldiers causing casualties and on the top of the table are tech levels of soldiers recieving casualties. With knowledge from the part about CRT I think that you needn't more explanations of these tables and you will read them (and modify) without problems.

For those who want some good explanation:
If you remember the soldier with sword, each line in this file is for soldier with different weapon. In vanilla Eu2 the first line are soldiers with swords, the 4th for example are soldiers with muskets (I'm not counting the line where are names of tech).
And do you remember the T-Shirt? Then each row in this file is for man with different T-Shirt, suit or shield.
Now you must use your knowledge of the weapons and suits/shields of the period for which you're making the modification and place these weapons/suits in your mind to right tech levels.
Then use your imagination and in mind try to use each weapon against each suit. Write letters closer to A when the damage by the attack should be like massacre, and write letters closer to E when the attack should be not so bloody.

So here you can modify how bloody will be attacks (the damage of attacks) of soldiers with different tech levels against soldiers with another tech levels.

Great explanation, ThankYouVeryMuch
It'll come to good use some day

Indeed Kaigon, this explanation is awesome... I never understood how the CRT thingy worked out, but with that little picture, now i do.

Thanks a lot for this KaRei!

P.S. in the bottom right corner you speak about a CRB, i supose you mean, CRT?

My mistake. CRT of course o

The artillery firepower is listed as 150, why do you have it 15,000? is it for each single artillery piece so multiplied 10?
The battle would have USA using table A in the shock phase which is another 1.0, so another 311 casualities, right? Seems like the shock phase is more though.
Also, during your tests, did you find how long each phase lasts?
Oh yea and along the same lines when are new rolls made?
Nice Work.

I deleted my older reply because of too much changes/edits. So here is the new one:

The artillery firepower is listed as 150, why do you have it 15,000? is it for each single artillery piece so multiplied 10?

Oh, a mistake. Its 15,000 but for 1,000 cannons, not for 10 as I'm using it.

The battle would have USA using table A in the shock phase which is another 1.0, so another 311 casualities, right? Seems like the shock phase is more though.

USA will be fighting in B columns in shock phase as in fire phase. Instead LANDFIRE.CSV we must take LANDSHOCK.CSV, but there we'll find:

MUSKETS;A;A;B;B;D;E;E

Third letter in line is for ARQUEBUS, a tech level of Rebels. We see here 'B'. So USA in shock phase will attack rebels with modificators from colums 'B'.
On the image are mistakenly swaped columns of morale and casualties modificators. So 15% modificator in line 8 will be used instead the 1%.

Also, during your tests, did you find how long each phase lasts?

Each phase takes 5 days.

Oh yea and along the same lines when are new rolls made?

New rolls (new random numbers) are choosed at the beginning of each phase. These rolls are used during WHOLE PHASE (5 days).
Attacker and defender could have different rolls.
(For those who are confused by "roll": it means the line in CRT tab and during the battle it's changing only because of different random number used in the first equation. This random number is changed each 5 days).

EDIT: Picture in the first post is now corrected.
