ChappyCanuck Posted April 3, 2018 Share Posted April 3, 2018 I was recently playing the CMFI battle, "Alvano Anvil", with a friend. Two of my Pak40's were out of sight and spread far apart from each other. They were suffering no incoming fire, indirect or otherwise, and my friend confirmed that they were not targeted. At the EXACT same second of the same turn, both crews experienced a mysterious casualty and subsequently abandoned their guns. Their ammo bearers also panicked and ran at the same time although they did not suffer the mysterious casualty. I can only assume this is a glitch of some sort. In any case, I have kept the file. Has this ever happened to any of you? Cheers 0 Quote Link to comment Share on other sites More sharing options...

Vergeltungswaffe Posted April 3, 2018 Share Posted April 3, 2018 In almost 18 years of CM gaming, I have seen ricochets do all sorts of chicanery. 1 Quote Link to comment Share on other sites More sharing options...

ChappyCanuck Posted April 4, 2018 Author Share Posted April 4, 2018 Except that my guns were on a reverse slope, there was no incoming fire, and they were about 200 meters from each other and both happened at the exact same second. Bizarre! 0 Quote Link to comment Share on other sites More sharing options...
c3k Posted April 4, 2018 Share Posted April 4, 2018 LOL...Poor Hans. 1. I think it's pretty awesome that this type of frag damage is simulated. 2. Now you know why NO ONE hangs out near tanks. 0 Quote Link to comment Share on other sites More sharing options...

What happens is that the enemy shell hits the tiger and ricochets into the ground immediately in front of the tank. If you watch closely, you can see the explosion. In the old engine, such ricochets would explode on contact, and the explosion would be strangely powerful compared to the size of the shell. I often noticed soldiers falling down though they were far from the point of impact. 13 minutes ago, c3k said: 1. I think it's pretty awesome that this type of frag damage is simulated. Well, it's not any more. It was later changed so that AP shell ricochets would not explode on hitting the ground. Later, the bug reappeared and was again fixed in the first CMFB patch. In short, I don't think this has anything to do with the issue of the original poster 0 Quote Link to comment Share on other sites More sharing options...

The AP shell exploded, based on the visual, and a guy got hit. As to the earlier issue with APHE being too powerful, well, as were others, I was a big part of the solution to that. Totally "read in" on it. This? This looks legit, to me. An energetic piece of metal hits an immovable object, there's gonna be chunks flying around. 0 Quote Link to comment Share on other sites More sharing options...

domfluff Posted April 5, 2018 Share Posted April 5, 2018 From previous discussions, I think the way that CM models fragmentation is that the explosion draws a number of ray-traces from the explosion point, in random directions. I assume that this number depends on the size or how fragmentary the round is supposed to be. Assuming these are just straight line traces (an assumption with no firm basis), this could produce some really weird results in the occasional edge-case scenario - hurting people across the map, and so forth, assuming there happened to be nothing in the way. I know I've certainly seen people get injured unexpectedly from incoming rounds, so that might be what's happening here. It would certainly explain the simultaneous losses. As a rule of thumb, "Danger close" is always further than you expect. 0 Quote Link to comment Share on other sites More sharing options...

As a rule of thumb, "Danger close" is always further than you expect. There's a distance limit. From what I've seen, the maximum casualty distance from an explosion in metres is roughly equivalent to the size of the shell in millimetres. 75mm HE = 75m danger range. (actually a bit more, but it's a useful rule of thumb) Edited April 5, 2018 by Bulletpoint 0 Quote Link to comment Share on other sites More sharing options...
domfluff Posted April 5, 2018 Share Posted April 5, 2018 Yeah, I expect there's a limit. It's definitely more than calibre-in-metres though. Doctrinal danger close is something like 200m for a US 60mm mortar (IIRC), although sensibly that would include scatter from incoming rounds, etc. 0 Quote Link to comment Share on other sites More sharing options...

domfluff Posted April 6, 2018 Share Posted April 6, 2018 Yeah, that's lethal range - that's the range you expect people to die, rather than the range that they could get hit. An important distinction if they're your own guys From the current US Infantry Manual (there's little difference in basic HE mortar effects from WW2 to now, so the values are still valid) MSD = Minimum safe distance PI = Percentage of incapacitation. 0.1 is one in a thousand soldiers will be incapacitated at this range, in expectation. 10 PI is one in ten (i.e., you expect to cause casualties with a mortar round at this distance). Below the above table there's: "WARNING REDs are for combat use and do not represent the maximum fragmentation envelopes of the weapons listed. REDs are not minimum safe distances for peacetime training use." 3 Quote Link to comment Share on other sites More sharing options...
MOS:96B2P Posted April 6, 2018 Share Posted April 6, 2018 3 hours ago, domfluff said: Interesting table. Thanks for posting this. +1 It also shows that @Bulletpoint rule of thumb is fairly accurate if you compare it to the right column (10 PI). As a player I know I probably push the pixeltroopen more than I would if they were real soldiers. So that 10 PI column and Bulletpoint's rule of thumb work well for game purposes. 0 Quote Link to comment Share on other sites More sharing options...

Yeah I think it matches pretty well too. At least for a basic guide to stick to. Seems the game got the max distances pretty much right.. I'm quite surprised to see there's still a tiny risk of getting hit at 175m though, for the 60m mortar. I'd assume any fragment would be stopped by air resistance at that range. Not doubting the army findings of course. I'm pretty sure they know what they're talking about - I'm just surprised.

Bulletpoint Posted April 6, 2018 Share Posted April 6, 2018 I wonder what the "certain death" ranges are for the various shells against prone infantry. I'm playing a game right now where I had two guys prone - one took a nearly direct hit from what seemed to be a 105mm... he died but the other guy was fine 2 metres away from the crater. 0 Quote Link to comment Share on other sites More sharing options...
Erwin Posted April 6, 2018 Share Posted April 6, 2018 Yes, seen that a lot. You can blast an enemy position with heavy HE, but when you attack maybe 30 seconds later the enemy pops back up and do a good defense. Just a vagary of the system... 0 Quote Link to comment Share on other sites More sharing options...
