AARHE: Phase 3: land Combat

The on going discussion:
http://www.axisandallies.org/forums/index.php?topic=40520.msg1693864#msg1693864
on Transport with defense roll makes me wonder about actual combat strength of Classic Transport and an escorted TP:

Transport and Destroyer A2 D2 C15, 1 hit
Offense & Defense factor:
36*(2/15^2) = 0.32

Transport and Cruiser A3 D3 C19, 1 hit
Offense & Defense factor:
36*(3/19^2) = 0.30

Classic Transport A0 D1 C8, 1 hit
Defense factor:
36*(1/8^2) = 0.5625

I revised the opening post.
As comparison points, a Fighter A3 D4 C10 off/def is 1.08 / 1.44

Destroyer A2 D2 C8, 1 hit
Offense & Defense factor:
36*(2/8^2) = 1.125

Submarine A2 D1 C6
Offense:
36*(2/6^2) = 2.00
36*(3/6^2) = surprise strike 3.00
Defense:
36*(1/6^2) = 1.00
36*(1.33/6^2) = surprise strike 1.33

You need to send 2 Destroyers to get a similar defense value with Classic Transport strength 0.5625:
Transport and 2 Destroyers A4 D4 C23, 2 hits
Offense & Defense factor:
36*(2/11.5^2) = 0.544

Or make defenseless Transport a 4 IPCs unit:
Transport and Destroyer A2 D2 C12, 1 hit
Offense & Defense factor:
36*(2/12^2) = 0.50

Now, if you want to introduce a Classic TP with the same strength of actual DD+TP combo 0.32:
You need to make TP cost 10,5 IPCs:
Classic Transport A0 D1 C10, 1 hit
Defense factor:
36*(1/10^2) = 0.36

At 11 IPCs, it would be 0.30 though.

Transport defending A0 D1 would be interesting at a clean 10 IPCs.

@barney:

wow
I thought I could just read this and not have to think :)

Sounds way cool. I wonder how it will effect naval battles? In a good way I’m thinking
Yea I 'm gonna try it :)

Well I just read the whole thing! And yea sounds better.
Have you played any games yet?

I playtested this last one:
@Baron:

So, I tried with a better success this much more stable (and simpler) values for Fighter and Tactical on defense and only Tactical Bomber get bonus on attack for specific situations:

FIGHTER
Attack 2, same in SBR
Defense 2 or 3, same in SBR
Move 4
Cost 7
1 hit
Air combat unit, Fighter as an Air Superiority aircraft:
All hits are allocated to aircraft units first, if any available.

Combined Arms Bonus:
Gives +1 Attack to any Tactical Bomber paired 1:1 with.

Fighter as part of an extended Air Defense System:
Up to 3 Fighter units receive +1 Defense if protecting a territory with an operational Air Base, (or 1 Fg for a Victory City if playing 1942.2)

TACTICAL BOMBER
Attack 2 or 3 or 4, SBR @1
Defense 3
Move 4
Cost 8
1 hit
Combined Arms bonus, Tactical Bomber as a less vulnerable “Dive” or “Torpedo” Bomber when escorted by Fighter:
**_Gain +1 Attack, when paired 1:1 with a Fighter .

Air Supremacy Bonus, Tactical Bomber as a “Dive Bomber”:
Gain +1 Attack when no ennemy’s aircraft is present.
These two bonuses can be added to raise up to Attack @4.
With these other units:

STRATEGIC BOMBER
Attack 4,  SBR @1
Defense 1
Move 6
1 hit
Cost 10

Strategical Bombing Raid (SBR*): Attack @1
SBR damage: 1D6+2 on Industrial Complex, Air Base or Naval Base

Fighter: Attack 2 Defense 2 or 3
Tactical Bomber: Attack 1 Defense 0
Strategic Bomber: Attack 1 Defense 0

DEFENSIVE MANEUVERS allowed for all 3 types of aircraft:

Aerial Retreat for attacking planes (all aircrafts can retreat while letting ground units pursuing battle),

Limited Aerial Withdrawal of 1 space in a friendly territory after first combat round for defending planes up to 2 StBs or 2 TcBs or 2 Fgs.

a limited landing in a just conquered territory: 2 planes (either Fighter or Tactical Bomber), as long as it can provide 1 extra movement point for this special landing.

FLEET CARRIER G40
Attack 0
Defense 2
Move 2
Cost 16
2 hits
Hold up to 3 planes : 3 Fgs / or 2 Fgs and 1 TcB / or 1 Fg and 2 TcBs / or 3 TcBs.
A damaged Aircraft Carrier still allowed flight operation for 1 plane unit.

FLEET CARRIER 1942.2
Attack 1
Defense 2
Move 2
Cost 14
1 hit
Hold up to 3 planes : 3 Fgs / or 2 Fgs and 1 TcB / or 1 Fg and 2 TcBs / or 3 TcBs.

ESCORT CARRIER
Attack 0
Defense 1
Move 2
Cost 9
1 hit
Hold 1 plane : 1 Fg OR 1 TcB.
ASV: Anti-Sub Vessel, same as Destroyer against Submarine.

CRUISER
Attack 3
Defense 3
Move 2
Cost 10
1 hit
1 Shore Bombardment @3.

BATTLESHIP
Attack 4
Defense 4
Move 2
Cost 18
2 hits
1 Shore Bombardment @4.

On a battlecalc, these values gives similar odds of survival to a full Carrier with 3 TcBs against itself when 1 CV and 2 Fgs attacks 1 CV and 2 Fgs. You get similar odds about 1 CV, 1 Fg, 1 TcB against itself compared to 1 CV 2 TcBs and 1 Fg against itself (as far as I can put similar numbers in the calc).

The idea is that a full Carrier is better on defense than offense.
So, to keep this principle in line, TacB has been put to a single defense value of 3.
It is slightly higher than Fighter (keeping @2), but remember that Fighters always hit planes first.

The 3-planes carrier provides more units in a SZ and Fgs A2 D2 C7 can be a good fodder instead of loosing a costlier Carrier with the same defense @2.
So during combat rounds, usually owner’s will keep Carriers and sacrifice Fighters and it doesn’t change the defense factor.
That’s the main difference with OOB Naval Combat, often Carriers with lower Def @2 are sacrifice earlier because of the high defense value of Fighters (D4).

Also, 3-planes Carrier gives more strategy and flexibility on which units (Fg or TcB) you prefer to put on board.
All 3 cheaper Fighters (A2 D2 C7) but with lesser odds A6 D6 C21.
All 3 costlier TcBs (A2-3-4 D3 C8) better on defense but not good against an opponent defending with planes (A6 D9 C24).
The mix of both Fg and TcB is far better in combat 1 Fg & 2 TcBs or 2 Fgs & 1 TcB.

I also like to put small 1 plane-Escort Carrier (A1 D1 C9) (bought from HBG) in the roster.
Their relative strength toward 3-planes Fleet Carrier is better historically depicted.
In fact, a single Escort Carrier can carry around 27-33 planes while a Fleet Carrier is around 90-100 planes.

I also experimented a Fg unit attacking @1 with First strike and defending @2 but the very low value of 1 and specific First Strike ability similar to subs was slowing down the battle process.
That’s why I prefer the A2 D2 C7 Fighter.
(Combat values wich are also similar to 1914 planes. From a A&A game franchise consistency POV.)
In each combat round, you start by rolling both attacking and defending Fighters, then picking up casualties on planes.
After, you continue with regular combat unit rolls.

One historical objections I made to myself was about that Fighters were better defending than attacking.
I answered it by giving a special +1 defense bonus to 3 Fighters when an operational Air Base is present.
This could figure the alertness of interceptors and all the Radar and Survey system against incoming planes.
Also, defenders can also have AAA unit on their side to increase the casualty rates of attacking aircrafts.
That’s why I think it can still be acceptable from an historical POV.
(Also, don’t forget how G40 OOB SBR rules doesn’t care about it, giving all planes a roll @1.)

TacBs Attack 2-3-4 Defense 3 values were more dictated by the defensive capacity required for Carriers to keep the similar balance of their OOB counterpart.

Strategic Bomber are lowered to 10 IPCs and it is required because of the dangerousness of attacking defending Fighters. Each round they could shot it down, no matter the number of ground units for fodder.

Finally, Cruiser and Battleship’s cost are reduced by 2 IPCs, 10 and 18 IPCs to level them against a more dangerous Fleet Carrier at full strength and cheaper planes.
To fully compete with this new carrier (which is a bit better than the regular OOB), it is now a must from the Battlecalc POV that Battleship and Cruiser need a reduced cost of 2 IPCs :
Cruiser A3 D3 M2 should cost 10 IPCs while Battleship A4 D4 M2, 2 hits should cost 18 IPCs.
So, Cruiser will be at the same cost than Strategic bomber (A4 D1 M6 C10),
and the Battleship (18 IPCs) still compete against the Cruiser (10 IPCs) + Destroyer (8 IPCs) combo.

Example: 12 Fgs gives A2 D2 C7, are too powerful against 7 A3 D3 C12 Cruiser.
Overall %*: A. survives: 94.8% D. survives: 4.7% No one survives: 0.5%

10 Fgs gives A2 D2 C7, are within acceptable margin against 7 A3 D3 C10 Cruiser.
Overall %*: A. survives: 75.2% D. survives: 23.2% No one survives: 1.6%

All in all, the additional money made from this savings will be needed to replace for the increased rate of aircrafts casualties.

From my little experienced with 3-planes Carriers, it works well.

Also, if you really want to increase aircrafts combat interactions in contested land territory, you should allow attacker to land a single Fg or TcB, or even up to 2 aircrafts in a just conquered territory.
(I ruled that an additional movement point to land in this zone is required.)
Otherwise, your game would mostly relied on AAA to defend against attacking planes.

I will post something on AAA issue in another thread more sooner than later.
For now, just know that I put them at 3 IPCs to get the maximum incentive to buy them.

Hope you will try and enjoy it.

One little physical inconvenient about a fully loaded Carriers unit with 3 TcBs is that there is not much place on the sculpt to put them in a row.
To overcome the lack of room for this bigger sculpt, is to put a chip on a Carrier below a TcB sculpt for additional units.
On the brighter side, any mix with a smaller Fg sculpt fit well on top of a Carrier._**

@Baron:

A2/D2/M1/C6-ACA1/ACD1   The AAA is now considered artillery in general combat. It still functions as an AA gun in the AC phase but attacks and defends on a 1:1 ratio in all combat phases. This promotes purchasing and breathes some life into this potentially interesting piece.

First time I saw this way of playing it. Original one!

Yeah I see no reason why this unit needs to function as it does. We have built-in AA on facilities now. So why not try doing something different with a unit that has potential?

@Uncrustable:

Tac bombers need something, they are rarely produced relative to fighters and strat bombers

I would also suggest letting tanks roll a 4 for each tac bomber present if air supremacy has been achieved, that is for each tac bomber one tank rolls at 4 instead of 3. Tac bombers do not change
This even further increases air buys and also gives tanks a buff which they need

We already have a round of combt befor normal combat (AAA) just add all planes to that round, everything hitting on 1s. Easy

Air supremacy is checked for each round of combat, before any dice are rolled for that round

These rules will magnify both fighters and tac bombers buys as well as tanks, and also promote a combined arms approach to purchases similar to artillery and infantry

You want enough fighters to achieve air supremacy, but also a good even amount of tac bombers and tanks to maximize air supremacy when you do achieve it

This kills multiple birds with a single stone
It should reduce somewhat the infantry/mech spam with sprinkles of artillery that we see now
It also indirectly buffs AAA as each AAA adds 3 more dice to the air battle in defense, and increases your chance of gaining control of the skies

Very thoughtful ideas. I like them.
However my first impression is your HR change much more the balance.
I’m looking for just small changes.
I will come back on this.
You have some compelling reason like this one:

We already have a round of combt befor normal combat (AAA) just add all planes to that round, everything hitting on 1s. Easy

Thank you very much for your challenging ideas.

Look you just tell me what you want and ill make a custom map (from my AA50) just for you to print off.

thats fair enough. But just don’t ask for all kinds of changes. I can make a few new territories and some changes, but i wont be making or drawing major modifications.

AARHE stands for Axis and Allies Revised: Historical Edition.

A set of house rule with enhanced realism, to be used on top of LHTR 1.3.
Comes with historical justifications in italics for each rule.

The two stickied threads has the files.

Admiral: I know where you got your name!

anyway a national unit value list would be possible only with a d12 system goto harrisgamedesign and you will find the official way how we did it over at his site.

called d12 unit value list.

replace
“its income cannot be spent in other territories.
That income and only that income can be spent in its IC or VC during purchase units phase this turn.
That income is forfeited if not spent this turn.”

with
“The blockaded territory’s income can only be spent in its own VC or IC. Income from other territories may not be spent in the blockaded territory’s VC or IC.
If the blockade territory’s income is not spent this turn it is forfeited.”
