River crossing and flawed shock attacks
Hi
I have seen this in the past already and it came up last turn again. I have an army of over 2000av in a base in China (Chikiang sp?) and a small unit comes in from another direction crossing the river and triggering a shock
attack. Now I am fine with the unit having to do a shock attack, but it also triggers the whole Army there to do a shock attack. Now if it would be at least a real working shock attack, but it isn't. All that
happens is my full army taking the losses as if they all would shock attack, but they a) don't lower forts b) don't do any damage to the defender and c) they take the full losses of a shock attack. What seems
to happen is a shock attack of the crossing unit and then the game turns crazy, dishing out damage to all units that are in the hex already but those units don't do any damage in return.
In the end, I have several trashed units, have done no damage to the defender at all and none of the "pseudo shock attacking" units have taken disruption or fat, which makes me sure that this is nothing but flawed.
I know that river crossings result in shock attacks, but the crossing units should shock attack and not the units that are already across the river. And if they attack, then I think they should really attack,
not just take horrible losses for no gain. Safe attached.
edit: and here's the combat report just to give you an idea. A unit with a couple of hundred men crossed the river, the whole army is triggered, takes horrendous losses and scores what? Not a single Chinese casualty with
an adjusted av of 0?

RE: River crossing and flawed shock attacks
That seems really strange to me. Once it was not like that, at least I've never experienced anything like that.
But for sure, if that's the new behaviour of the latest beta, there's something that needs to be changed!

RE: River crossing and flawed shock attacks
In the Betas (but not really recent Betas) I have seen shock attacks in those situations that went properly, meaning that it was clear from the results that only the proper unit made a shock attack. I assume this situation that Castor ran into snagged some bug that Michael is trying to ferret out.

yeah, usually my shock attacks work as designed but that one clearly wasn't when only that Chinese btn should have shock attacked crossing the river through an enemy ZOC.

Saw a similar situation river-crossing shock attack in my game with latest Beta (x4) last turn. It went properly with it obvious that only the crossing unit shock attacked.ORIGINAL: GreyJoy

So at least we know the bug does not happen all the time.

I'll have a look at the save later in the week to understand what was triggered.

RE: River crossing and flawed shock attacks
Explanation:
This attack was caused by one unit (#8020) moving from (78,51) to (78,50) - lower right hex to the base hex.
1. Both sides of the hex were not controlled by Japanese as shown in image - there is a green/red color to the hex-side between them along the river.
2. Nor are both hexes Japanese controlled. Thus it is treated as a contested move.
3. Shock attack is made if
a) the total attacking AV is less than 1/3 of the total defending AV at the start of the move - for this move attacker AV was 2326, and total defender AV was 3795, so this did not apply. [Beachhead rule]
b) hex-side moving into is enemy controlled - which it is from image.
This is how it has been since patch 3.
The unit moving from the east hex across the river wont cause a shock attack as both hex-sides of the river between them is J controlled.

RE: River crossing and flawed shock attacks
I look up unit 8020 at the start of the turn, and it actually warned you that it was crossing an enemy held river.
Stopping this unit from moving across river does remove the shock attack.
To make the hex-side J controlled I think, needs a J unit to move across it to the other hex where unit 8020 is. Or only J units in hex to control all 6 sides

RE: River crossing and flawed shock attacks
I think that Castor's report was different - that since only the one unit moved in, only the one unit should have shock attacked, but judging by the casualty figures it was all units that shock attacked.

RE: River crossing and flawed shock attacks
Combat in a hex involves all available units. Not sure how that would apply if only one unit was set to Shock.
[I'll try to see how that applies]
It uses the highest attack level for the hex combat (Shock in this case is the highest). But that might only be for the general combat type.
Terribly confusing...this may take a bit of time
Lucky there is only 2 ground combat sessions in the turn[:D]

RE: River crossing and flawed shock attacks
I can say for certain that with the same version (x4) in my PBM we recently had a combat where, with a bunch of units already in the hex, one more crossed in, and that unit did shock attack. But the other units did not shock attack (they had player-given orders to 'defend'), which is the behavior consistent with how it has been for a long time. We were able to tell that from the casualty list, which was very small and (in this case) would have been far larger had all units shock attacked.
Not sure what the difference is. But, I just checked and I still have the saves from that turn. In case it helps for comparison, here is the combat report snippet and the combat replay is attached. Let me know if you need a full save.

RE: River crossing and flawed shock attacks
The list of assaulting units is misleading. The list is of any unit that is involved in the combat - bombardment, engineers, actual assault troops.
From what I can see so far, only the units that have a shock attack actually assault the enemy. The other non-defending stance units will supply artillery and maybe some combat engineers to the attack which will assume a 'bombardment attack' stance.
However, the enemy will target any non-defending stance units in the hex for return fire.

RE: River crossing and flawed shock attacks
In the case of my PBM, Walter had no units attacking or bombarding, just the unit that crossed in fresh made its shock attack. In Castor's case, I don't know if he had other units bombarding or something as I didn't see that in his post. Are you saying that his other units were bombarding and therefore that is why they were subjected to fire from the defenders once the crossing unit shock attacked? (Restating it my own way to make sure I understand it.)
In any event, it's late here so I am attaching that full save just in case you decide you want it (no harm done if you don't need it).

RE: River crossing and flawed shock attacks
Yes, there were bombarding units. I'm trying to determine what the loss rate was before actual assault.
From what I can tell the majority (if not almost all) are due to enemy bombardments.
There may be a problem in that defending units in 'defend' or 'bombardment' appear to be using all devices to counter-fire against a unit firing in bombardment mode. So while the attacker can only use ranged weapons, the defender in position can use all weapons.
Result of combat with adjusted rule:
This seems more in line with units shelling each other, while one unit shock attacks across the river.

Adjusted rule would be:
In defensive fire against a bombardment attack, only ranged weapons (as would be allowed in a bombardment attack) are fired in the defending unit if it is in 'defend' or 'bombardment' stance.
This might make bombardments less bloody to the attacker.[&:] Especially against units with few ranged weapons.
I'll create an updated EXE to attach here for players to try out later today.
Note that this applies to all such combat. The river attack above just made it stand out.

RE: Adjusted exe for bomardments only attacks
Here is a EXE to try out. Just unzip into the Beta2 directory.
Changed Limit the return fire from LCU in defend/bombard stance when being attacked by a enewy LCU in bombard stance.

RE: Adjusted exe for bomardments only attacks
Using it and so far looks good. I haven't had many grounds yet, but the few I have had did not look disturbing.
Pax
RE: Adjusted exe for bomardments only attacks
Are there any unexpected side-effects? For example,
1. If the defense only fires its artillery, does that mean it is now possible to bombard Chinese units without giving them a big boost in experience?
2. Does this mean the intel on the defense given in the combat report no longer includes all the strength of the defenders? E.g. omitting units that have no artillery.
3. Does this reduce the amount that the defending units supply demand increases, because only part of the units fire? Do units without artillery not increase their supply demand at all?
Not saying these are bad changes to make but it would be worth knowing all the consequences of such a change.
