  1. 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.
  2. Yes, and the direction of the wind does not appear to matter. The mortar was about 400-500 meters to the left from the target below if my memory serves.
  3. Thanks everyone, I enjoyed sharing and discussing this stuff here. I believe that this time, the will of the man outlasted the will of the machine. It played thousands of hours of CM.
  4. The latest - and last - update of spotting ability, with German tank destroyers and assault guns added. No big surprises there. It is the last update because my old computer started complaining loudly about the ordeal I've been putting it through. I still want to squeeze a few more miles out of my old friend, so I promised him no more CM testing.
  5. 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.
  6. I have the same problem in my CMRT (non Steam, obviously). When saving, I must specify a unique file name, otherwise the game fails to overwrite the old file, and nothing is saved.
  7. Yes - I don't know about tank gun ballistics, I just know that a Pz IV shooting at another, fully exposed Pz IV at 600 meters misses about 68% of its first shots in CM. If the target being hull down changed that to, say, 80%, we would see it in the results - the hull down tank would retain its advantage even when spotting is taken out of the equation. We would see that even if the 3rd and subsequent shots are sure hits. But we don't see that. However, it is not a direct proof that the hull down tank is not less likely to hit. It is just implied by two series of tests that measured something different. I would have to measure the probability of hitting a hull down target directly.
  8. In CM, this is actually not true - a shot fired at 600 m is not a sure hit. Below is a printout of my gun accuracy tests for the Pz IV, with Regular crew, no modifiers, target Pz IVH fully exposed on flat ground. The probability of hitting with the first shot is around 32% (highlighted). Therefore, there is room for the hull down position to make a difference in the chance of hitting. But that's apparently not happening.

With fewer hits I would probably need to test for much longer to get good statistics. But at some point I might test the probability of the first shot hitting a hull down tank at different ranges and compare.
  9. I ran my usual 1000 trials with one Pz IV in partial hull down position vs one Pz IV in full hull down position. Regular, no modifiers, 600 m, crew hatches open. In the first round, neither side had a contact, so both spotting and shooting accuracy would determine who wins. The result was 39:57 - the hull down tank had a significant advantage. In the second round, I used target arcs to prevent both tanks from shooting until both had full contact on each other. Therefore, they would start shooting almost simultaneously and only the shooting accuracy (and protection) would determine who wins. The result was 56:47. I repeated this run with another 1000 trials, the second result was 54:50. The average of all 2000 trials was then 55:49. The hull down tank has a slight disadvantage. It might be due to the poorer protection offered to the hull down Pz IV by the turret armor vs upper hull. I see no indication that a hull down tank is harder to hit at this range than a more exposed vehicle. I think it is in agreement with @Pelican Pal's findings.
  10. I think this is an interesting find, whether it is "actionable" or not. It is good to know if hull down makes you harder to hit - and survive, if your turret armor is weaker than the hull. It is difficult to apply the idea "relocate to a non-HD position once spotted". Too much happens in one minute of the action phase - in one minute the duel may already be decided. Besides, once the fight is on, I'd rather sit and shoot than maneuver under fire. But everyone can make their own conclusion from what you found out. I'll see if I can confirm.
  11. Nah, you can't derail this thread with just one bulletpoint I don't expect any surprises about their spotting, either. It is unfortunate that they don't come up more often in QBs - German armored cars in general - they are interesting vehicles. Too expensive. Stuarts can do more for less.
  12. I've never thought about it that way, but I think I've seen similar things happen - I doubt they are specific to AA guns vs Puma, it is more likely that they apply to all crewed weapons vs AFVs. I agree that units see the crew and not the gun - when the crew take cover and vanish from sight, the unit is unable to spot the gun itself and loses a target to shoot at. I also think that the AI tries to choose the weapon that "makes most sense" to it in a given situation. When the crew is up and vulnerable, it may be worth a HE. Once they take cover, the AFV will use MG to keep them suppressed, although we might prefer using more HE to blast the gun out of existence before it gets the chance to shoot back. My tests won't help here. I will only tell you how well the Puma can spot compared to other AFVs.
