      Special Upgrade 4 Tech Tips   12/27/2016

      Hi all! Now that Upgrade 4 is out and about in large quantities we have now discovered a few SNAFUs that happen out in the scary, real world that is home computing.  Fortunately the rate of problems is extremely small and so far most are easily worked around.  We've identified a few issues that have similar causes which we have clear instructions for work arounds here they are: 1.  CMRT Windows customers need to re-license their original key.  This is a result of improvements to the licensing system which CMBN, CMBS, and CMFB are already using.  To do this launch CMRT with the Upgrade and the first time enter your Engine 4 key.  Exit and then use the "Activate New Products" shortcut in your CMRT folder, then enter your Engine 3 license key.  That should do the trick. 2.  CMRT and CMBN MacOS customers have a similar situation as #2, however the "Activate New Products" is inside the Documents folder in their respective CM folders.  For CMBN you have to go through the process described above for each of your license keys.  There is no special order to follow. 3.  For CMBS and CMFB customers, you need to use the Activate New Products shortcut and enter your Upgrade 4 key.  If you launch the game and see a screen that says "LICENSE FAILURE: Base Game 4.0 is required." that is an indication you haven't yet gone through that procedure.  Provided you had a properly functioning copy before installing the Upgrade, that should be all you need to do.  If in the future you have to install from scratch on a new system you'll need to do the same procedure for both your original license key and your Upgrade 4.0 key. 4.  There's always a weird one and here it is.  A few Windows users are not getting "Activate New Products" shortcuts created during installation.  Apparently anti-virus software is preventing the installer from doing its job.  This might not be a problem right now, but it will prove to be an issue at some point in the future.  The solution is to create your own shortcut using the following steps: Disable your anti-virus software before you do anything. Go to your Desktop, right click on the Desktop itself, select NEW->SHORTCUT, use BROWSE to locate the CM EXE that you are trying to fix. The location is then written out. After it type in a single space and then paste this:

      -showui

      Click NEXT and give your new Shortcut a name (doesn't matter what). Confirm that and you're done. Double click on the new Shortcut and you should be prompted to license whatever it is you need to license. At this time we have not identified any issues that have not been worked around.  Let's hope it stays that way Steve

      Forum Reorganization   10/12/2017

      We've reorganized our Combat Mission Forums to reflect the fact that most of you are now running Engine 4 and that means you're all using the same basic code.  Because of that, there's no good reason to have the discussion about Combat Mission spread out over 5 separate sets of Forums.  There is now one General Discussion area with Tech Support and Scenario/Mod Tips sub forums.  The Family specific Tech Support Forums have been moved to a new CM2 Archives area and frozen in place. You might also notice we dropped the "x" from distinguishing between the first generation of CM games and the second.  The "x" was reluctantly adopted back in 2005 or so because at the time we had the original three CM games on European store shelves entitled CM1, CM2, and CM3 (CMBO, CMBB, and CMAK).  We didn't want to cause confusion so we added the "x".  Time has moved on and we have to, so the "x" is now gone from our public vocabulary as it has been from our private vocabulary for quite a while already.  Side note, Charles *NEVER* used the "x" so now we're all speaking the same language as him.  Which is important since he is the one programming them

Gents, I am currently playing the Germans in “Dies Irae“ and wonder, that I have two PAK’s (one 50mm and one 75mm), which each have a few (say two each) 150mm rounds available.

Does anybody know what that is?

Google it, yes it is real. It comes up periodically on the forum 

 

hmm wiki doesn’t have much but one of the grogs here will know.

There's good reference material for the 37mm gun version but references to the bigger calibers are proportionately difficult to locate. I've seen perhaps one or two rather sketchy references on the 50mm version.

I believe it's the example on the extreme right in this image:

Hm, being the dull engineer again: Would not most of the propelling power go out off those holes? With no specific direction?

I‘d think: Fake.

@StieliAlpha  There's a 50mm tube inside the perforated section (it extends about 2/3 of the length and is just visible if you study the image carefully) that fits into the muzzle, the perforated part fits over the muzzle brake:

Oops, that drawing is interesting, indeed.

Of course, if they slid it over the muzzle brake, the thing needed holes to vent the gas. But, whoah, those holes must create havoc to any idea of a flight path. And the tiny find don’t look like they would help much.

Hmmm, would be interesting to talk to their engineers. I wonder what they thoughts, designing this thing. 🤔

TBH it was something of a desperation measure.....If the KV is about to roll over your firing pit, it's time to go for the 150mm HEAT charge, at that range the lack of accuracy doesn't matter. 

I really miss having KVs to scare the bejesus out of German tanks.....Would love to see some more Ostfront stuff in due course.

Yep, but why not use the same design as for the 37mm and get rid of the outer thing then?

Otherwise, I am impressed that you could read my previous post, so full of typos. One should not try to type in the commuter train...

Quite simply because the PAK-38 had a muzzle brake:

PAK-37:

The PAK-37's HEAT round also had holes to vent propellant, you can see them clearly here:

PS - I believe that the cylindrical object by the gun's wheel is the ammo case for the HEAT round.

Ahaaaaa! The 37mm HEAT is not slid INTO, but ONTO the barrel. Ok, that explains something. But then the 75mm round is quite different. Really looks desperate.

Interesting, that the 37mm HEAT even has meaningful fins, compared to the tiny stubbles on the 75mm HEAT.

The PAK-38 is 50mm, but yeah that's the measure of it.....Keep in mind that these weapons were only intended as a temporary stopgap, to give the AT units some punch against heavy tanks, until sufficient 75mm PAKs became available.

Another interim AT gun from this period was the PAK-97/38, which placed a modified French 75mm on a PAK-38 carriage:

The holes helped.

Think about a badminton birdie. The lack of mass behind the cg means that the aerodynamic center is aft of the cg...leading to a stable, non-spinning, round. Or, to put it in "normal" terms: the center of mass is in the front of the object. The aerodynamic center is further aft. That's the role of the holed sleeve.

These would be fired with "blanks". They had extremely short ranges, so accuracy only had to be "good enough". (I have my suspicions that the main role was to keep the men's morale up so they would stay put when the enemy tanks first started coming their way. After that, it was moot whether or not they wanted to leave. They were already committed.)

Ahh. "Shuttlecock", as in all things from the motherland, sounds so much better. TBH, I was not fully caffeinated when I tried to pull the proper word. I shall reset the coffeemaker timer to an earlier hour so this will not happen again. ;)

Never mind guys. I played Badminton for more than 20 years (in my good times, five times a week), so I understood „birdie“ as well as „shuttlecock“. BTW, we called that thing just „shuttle“.😎

@c3k I understand the theory, still I think those holes look so brutal, that they would create turbulences, which would make a joke of anything like a straight flight path. Probably, the whole design was really more to bolster the confidence.

Guys, keep in mind that shaped charges were in their infancy at the time.....TBH it was probably considered something of a techno-marvel in its day (especially if you found your self looking at the business end of a KV-1).  ;)

Reminds me to the old Steel Panthers days, when in one campaign my tiny battle group met with a substantial KV-1 and T34 force for the first time. My only solution was to call retreat on turn 1. Better to live and fight another day.
