    Drifter Man got a reaction from LuckyDog in Some tank duel tests (CMBN)   
    I don't seek out armor duels because they are a bit like tossing a coin, but they come up again and again. So I was interested to learn what I can do to maximize the chances for my tank in a duel if it gets into one.
    So I put two identical Pz IVH (late) tanks with regular crews, no modifiers, against each other at 600 m range. I called one "Attacker" and the other "Defender", although it does not mean anything. I put both on a mild slope (partial hull down) and varied different conditions. Crew hatches open/closed, vehicle movement, terrain type, crew experience. I ran each case at least 1000 times and recorded the percentage of wins by each side. A 'win' means that the other vehicle was destroyed or the crew bailed out. If both vehicles were alive after 5 minutes, neither side won - usually one vehicle got hit and retreated back down the slope. If neither vehicle survived, both sides got a win.
    The tables show the win rate on each side. The statistics were not perfect even with 1000 duels per case. Results of repeat runs could vary by up to +/- 3%. Notably I did not get a perfectly symmetric results even for reference cases R1 and R4 where the vehicles had identical conditions on both sides. So, don't take the numbers as the absolutely accurate truth. They just show what works.
    Pz IVH was a good tank for this purpose because it can easily kill itself - powerful gun and vs weak armor. Therefore, the duels were mainly about who is able to spot first and land the first round accurately on target.
    I did not find anything revolutionary - mostly stuff people already know and do - but it was still interesting to see the numbers. Here it is:
    1. Keep your crew hatches open when expecting to fight an enemy AFV. If you can, force the enemy to close theirs.

    2. Minimize movement when within enemy LOS. Stop as soon as your vehicle can see the place where the enemy is (represented with the "Hull Down" command in the table below, which gives additional advantage of being harder to see and hit due to being hull down; this is not to say that the Hull Down command is always useable, but it worked here well because the Attacker was going up the slope). Movement makes you more visible - and it does not appear to matter what kind of movement command you use - in fact the faster movement commands seem to work a bit better.
    Table 2. Effect of vehicle movement. Attacker starts out of LOS and moves in towards the Defender using different movement commands. Both AFVs are on Grass and the crew hatches are open.

    Quick: Minimizes the time interval when the Attacker is moving within the Defender’s FOV. Therefore, Quick works well as it gets the attacker into position quickly, whereas Slow works poorly.
    Hull Down: Better cover than the Defender and minimizes time when the Attacker is moving within the Defender’s FOV. Also: Easier to disengage when damaged – probably for both sides. High percentage of duels with no winner.
    3. If you have to Hunt, point 1. about crew hatches still applies and can reverse the odds in your favor.
    Table 3. Effect of crew hatches open/closed while the Attacker is moving. Attacker starts out of LOS and moves in towards the Defender using Hunt. The Defender is stationary. Both AFVs are on Grass and the crew hatches are open.

    4. Target arc can serve various purposes but does not help with seeing or hitting the enemy. TRP helps, likely by increasing the chances of a first hit.

    Note: Target Arc can still help by pointing the gun and the Commander’s attention to the right direction if the vehicle is not moving directly towards the defender. Also, it prevents distraction of the Attacker by other, low-priority targets.
    5. Ground type can provide some help by concealment. Tall types of grass (T and TY), Weeds, Brush, Lt Forest (without trees) and Crop 1 give a small advantage over hard or bare surfaces. Very tall types of crops (2-6) and Grass XT give significant advantage. There is no disadvantage in being on road or pavement compared to grass, but sand, mud and cobblestone seem to hurt a little, possibly because they lower the chances of disengaging when retreating in damaged condition.
    Trees are complicated and depend on type. Type A trees are somewhat helpful if there are 2 or 3 on the tile. Type B trees are not helpful at all. Type C trees seem to be best, especially if there are 2 or 3. Type D trees are somewhat helpful independently on their number. Type E are like Type A. Bush does not make much of a change.
    Stone and brick walls and low bocage give some advantage - can be concealment as well as cover. But bocage is the big one. A tank behind bocage almost always wins against a tank in open ground.

    The assistance of infantry improves the chance of the attacker. The advantage provided by infantry is greater when both opponents are buttoned up. At this range (600 m), help of infantry makes the chances of a buttoned up vehicle approximately even against a vehicle with hatches open. It makes no difference if the infantry is on the tank as tank riders or on the ground nearby.

    Drifter Man reacted to Butschi in Script to automatically set the elevation in the editor   
    I wrote a little python script to set the elevation in the editor according to a digital elevation model. Those come in various resolutions, for instance, in Germany data for the whole of Northrhine Westfalia is available for free with a 1mx1m granularity. I then use PyAutoGui in order to automate setting the correcting height and clicking/scrolling in the editor. The script currently sets the height information for every square in the editor, not just contours.
    An example height map:

    The resulting terrain in the editor (3328mx1920m):

    Vista somewhere in there.

    The script is not terribly fast, making this map took about 7h, but it beats doing all the clicking yourself. The limitation, btw., is the editor, the script could go faster. The advantage is that you can do much better micro-terrain, I think, the disadvantage is that you can't just use an old topographical map and draw the contour lines. It would be possible to do contour lines but you'd need to have those in a machine readable format.
    Anyway, if people here are interested, I could polish the code a bit and make it available to everyone, e.g. via github. If there is additional interest, I could imagine doing other stuff that way, like, for instance, drawing roads from Open Street Map.

    Not much harder that the standard spotting and gun accuracy tests. One would just need to carefully remove the optics without breaking anything else, probably using an air attack.
    Unfortunately, with my backup laptop out of order, I had to put all testing on hold. It would be interesting to know the answer.

    Keep in mind that the mortar is to the left of the pictures above.
    So the shots with no wind have very little left/right drift, just the typical over/under variance, as you'd expect.
    But then, the 2nd and 3rd pictures, with high winds, show that the rounds are drifting in all axes, as you'd expect once again.
    Pretty well simulated imho.

    I have just tested out a few modes in CMRT and confirmed the save problem in:
    Single-player real-time (scenario) Single-player turn-based (scenario) Two-player hotseat (QB, scenario) Anything that goes into the Saved Games folder. There is no warning message. The player does not learn about the failed save until he tries to load it.
    In two-player PBEM, when attempting to save a new PBEM file for you opponent under a file name that already exists, the following message appears:
    Email save failed. '[name of the file, without extension]' could not be created in the Outgoing Email directory. Try again?
    Clicking 'Yes' allows me to change the file name and save successfully. Clicking 'No' returns me to the main menu. I suppose this is normal behavior of PBEM - it happens in CMBN and CMFI, too.

    I don't seek out armor duels because they are a bit like tossing a coin, but they come up again and again. So I was interested to learn what I can do to maximize the chances for my tank in a duel if it gets into one.
    So I put two identical Pz IVH (late) tanks with regular crews, no modifiers, against each other at 600 m range. I called one "Attacker" and the other "Defender", although it does not mean anything. I put both on a mild slope (partial hull down) and varied different conditions. Crew hatches open/closed, vehicle movement, terrain type, crew experience. I ran each case at least 1000 times and recorded the percentage of wins by each side. A 'win' means that the other vehicle was destroyed or the crew bailed out. If both vehicles were alive after 5 minutes, neither side won - usually one vehicle got hit and retreated back down the slope. If neither vehicle survived, both sides got a win.
    The tables show the win rate on each side. The statistics were not perfect even with 1000 duels per case. Results of repeat runs could vary by up to +/- 3%. Notably I did not get a perfectly symmetric results even for reference cases R1 and R4 where the vehicles had identical conditions on both sides.

    Pz IVH was a good tank for this purpose because it can easily kill itself - powerful gun and vs weak armor. Therefore, the duels were mainly about who is able to spot first and land the first round accurately on target.
    I did not find anything revolutionary - mostly stuff people already know and do - but it was still interesting to see the numbers. Here it is:

Stop as soon as your vehicle can see the place where the enemy is (represented with the "Hull Down" command in the table below, which gives additional advantage of being harder to see and hit due to being hull down; this is not to say that the Hull Down command is always useable, but it worked here well because the Attacker was going up the slope). Movement makes you more visible - and it does not appear to matter what kind of movement command you use - in fact the faster movement commands seem to work a bit better.
    Table 2. Effect of vehicle movement. Attacker starts out of LOS and moves in towards the Defender using different movement commands. Both AFVs are on Grass and the crew hatches are open.

    Quick: Minimizes the time interval when the Attacker is moving within the Defender’s FOV. Therefore, Quick works well as it gets the attacker into position quickly, whereas Slow works poorly.
    Hull Down: Better cover than the Defender and minimizes time when the Attacker is moving within the Defender’s FOV. Also: Easier to disengage when damaged – probably for both sides. High percentage of duels with no winner.
    3. If you have to Hunt, point 1. about crew hatches still applies and can reverse the odds in your favor.

    4. Target arc can serve various purposes but does not help with seeing or hitting the enemy. TRP helps, likely by increasing the chances of a first hit.

    Note: Target Arc can still help by pointing the gun and the Commander’s attention to the right direction if the vehicle is not moving directly towards the defender. Also, it prevents distraction of the Attacker by other, low-priority targets.
    5. Ground type can provide some help by concealment. Tall types of grass (T and TY), Weeds, Brush, Lt Forest (without trees) and Crop 1 give a small advantage over hard or bare surfaces. Very tall types of crops (2-6) and Grass XT give significant advantage. There is no disadvantage in being on road or pavement compared to grass, but sand, mud and cobblestone seem to hurt a little, possibly because they lower the chances of disengaging when retreating in damaged condition.
    Trees are complicated and depend on type. Type A trees are somewhat helpful if there are 2 or 3 on the tile. Type B trees are not helpful at all. Type C trees seem to be best, especially if there are 2 or 3. Type D trees are somewhat helpful independently on their number. Type E are like Type A. Bush does not make much of a change.
    Stone and brick walls and low bocage give some advantage - can be concealment as well as cover. But bocage is the big one. A tank behind bocage almost always wins against a tank in open ground.

    Sand, Mud, Cobblestone (?): Can impair movement, possibly making retreat of a damaged vehicle slower and less likely to succeed before the Attacker fires another accurate shot.

    Drifter Man got a reaction from Shadrach in Cant overwrite save files bug   
    I have just tested out a few modes in CMRT and confirmed the save problem in:
    Single-player real-time (scenario) Single-player turn-based (scenario) Two-player hotseat (QB, scenario) Anything that goes into the Saved Games folder. There is no warning message. The player does not learn about the failed save until he tries to load it.
    In two-player PBEM, when attempting to save a new PBEM file for you opponent under a file name that already exists, the following message appears:
    Email save failed. '[name of the file, without extension]' could not be created in the Outgoing Email directory. Try again?
    Clicking 'Yes' allows me to change the file name and save successfully. Clicking 'No' returns me to the main menu. I suppose this is normal behavior of PBEM - it happens in CMBN and CMFI, too.
