Enhanced Army Professionalism

Description
What Does It Do?

This mod, based upon the great "Military Reborned" by LoXyO, essentially improves Cavalry to make it worth keeping into late game, and simultaneously boosts Army Professionalism to make well drilled professional armies a force to be reckoned with on the battlefield (albeit with associated costs/high maintenance). The following changes have been implemented;

• For cavalry, the cost of each unit is now 15 ducats; cavalry speed has been boosted from 0.7-1.0, suppression and looting speed has also been increased, and cavalry now enjoy 15% higher chance of breakthrough.

• For infantry, they now have a 5% higher chance of breakthrough.

With regards to professionalism level and drill, the following has been tweaked;

• For units drilling, unit shock and fire damage are doubled; at 100% drill a regiment will have +20% shock, +20% fire damage. Fire and shock damage received is unchanged (this makes it VERY useful keeping your men at a high state of drill readiness).

• From 0-20% Professionalism, mercenary cost has been changed from -15% to -25%.
• At 20% Professionalism, building supply depots kick in, but so does the first stage of land maintenance cost (+10%).
• At 40% Professionalism, armies experience +10% defensiveness, but incurs a +25% land maintenance cost.
• At 60% Professionalism, you have +10% reinforcement speed, and also incur a +50% land maintenance cost.
• At 80% Professionalism, armies experience 10% morale recovery rate, as well as +1 free military commander, at the expense of +75% land maintenance cost.
• Finally, at 100% Professionalism, army fire & shock damage is doubled and you have +2 free military commanders, however, it also incurs an additional +100% land maintenance cost.

Additional Changes

• Rebels now spawn with less artillery.
• Garrisons will surrender if besieged and they have 300 men or less (not only giving purpose to the refill garrison ability, but also mitigating frustrating sieges where you instantly reoccupy a captured fortress and it's pristine/at full enemy strength).
• AI fleets have been tweaked to be a bit more combat oriented (more Heavy ships and less transport). Heavy ships now cost 40 ducats (down from 50).
• There is now a slightly higher chance of a military commander developing a new personality trait after a battle.


Compatibility:

Designed for EU4 1.36.*

Should work fine with most mods that don't touch army professionalism or attrition rates.

Unfortunately, it is not Ironman compatible. Sorry!

The other way around, it could be done by adding this line to the defines file.
NDefines.NMilitary.SLACKEN_AP_DROP = 0.01 -- changed to 0.01; original value is 0.05
So that you lose 1% army professionalism a year for 200% manpower recovery while active.

Huh... I confess I've never considered this (as I never slacken my recruiting standards personally - rather relying on mercs in such scenarios).

So you'd prefer buffing 1% to 5% cost annually? Or the other way around?

I think slacken recruitment standards cost needs to be changed from 5% yearly to 1% yearly, it was already seldom used in current patches but with professionalism buffed there's even less reason to use it.

You'd also help out some of the people who forget to turn their slacken modifier off for a few years.

NOTE: Updated to the latest version (1.36).

Also removed the drill decay modifier for professional armies - armies with high drill and high professional effectively never decay (or decay ridiculously slowly). As such, this should keep drill necessary even for professional armies late game to ensure additional combat effectiveness (on top of their professional tier buffs).

ya I kinda agree with khaos, drill is good at the start of the war, but within the first year or two (depending on attrition), it falls off very quickly. honestly I think professionalism should give units a certian amount of starting drill upon recruitment and reinforcement, since in the base game you apparently can have the most professional army on the planet but not even give units basic training before they recruit. maybe increase recruitment time for all units based on professionalism to account for the fact that they have a longer training time.

Hmm; if enough people request a change I'll implement it ;)

in imperator rome you gain army training with siege and battle, but not in EU4. also even at 75% drill decay less. you still lose entierely the professionalism after one or two year of war. it is not the month decay the problem but the decay you have with army battle loss and siege (because even at 1% attrition, one year of siege is 12% drill less and god know how long a war not cheesy can go)

Fair enough, but I personally disagree - I find that an undrilled army would rapidly lose discipline and effectiveness over time - the 0.06 modifier loss at max Professionalism as Prussia for example is a fair balance - easy to restore them to full drill anyways!

If there was a way to mitigate drill decay/skill via active combat that'd be great, but I don't see such an option at present in the code (AFAIK)...
Supermash May 22, 2023 @ 6:43am 
no the drill decay is too fast at max professionalism. if you combine max professionalism + sustained discipline (t5 governement) you would get only 58% drill decay which is very average for max professionalism

Do you mean you think drill decay is too slow?

I'm inclined to try and tweak it further.

As for siege ability, I often go for Ideas that boost siege ability so I have very fast sieges anyways. If others argue for boosts to siege ability I will make the changes.
