I made an excel 2010 file with a selection list and RE lookup for DPW. I think it needed to be 2007 or above (xlsx) in order to do the lookup.

I also did a E-Factor formula if you enter the mm or penetration
= 48 * 2.5^(3.322*(LOG(B13) - 1.4049))

You can use this if you have a prior version of excel where B13 is the pen value in mm.

I have never really used these formulas (my gaming system uses Guns, Guns, Guns), so if there are errors let me know.

For the excel file enter/select the data in the yellow fields and the results are in the green fields.

When I click on the attachment is downloads attachment.php, but if I rename it to "morrow_ex.xlsx" it works fine.

I'll go thru the formula to see how it stands up.

Thank you.

IE 11.

It is most likely something stupid with IE11 security settings.

I see where I was wrong with my formula in my spreadsheet of formulas.

Nice!

Thanks guys!

That will speed up dropping some new systems to equip Morrow Project encounter groups.

or if there is an Invasion USA! Gamer out there.

PAX-48, DNAN + NTO + HMX, Comp B, 1.00
PAX-21 DNAN + RDX + AP + MNA, Comp B, 1.00
PAX-41 DNAN + RDX + MNA, Comp B, 1.00

** Key ingredients is not really necessary, but interesting to show **

Terms Used;

IMX: Insensitive Munitions eXplosives
PAX: Picatinny Arsenal Explosive

Recoilless Rifle Munition M344A1
 
M344A1 HEAT

It uses 2.79lbs or 1 Kg of Comp B.

It will penetrate 300 mm RHA at zero degrees.

Updated!

nuke11 04-17-2014 06:35 PM

The Bofors 3A-HEAT-T uses 1 Kg of Octol, so it will have a DPW of 2678.

The M344A1 should be 1.27 Kg of Comp B, not 1.0 Kg as I stated. So it's DPW will be 2962.

If you don't already have one........ get an account for scribd.com.

Many military manuals end up there, I have the ammunition data sheets for reference. Some posted the 2011 World Wide Recognition guide from the DoD there too.

I worked this chart up awhile ago, and I like your chart as well. What do you think the AC is NIJ III+?

http://www.thesupplybunker.net/pdf/4...tings_v1.1.pdf

I'm working on an update for this chart as well. Transparent Armor (or Bullet Resistant Glass), is a little harder to find specs on it, but I'm making headway on this front.

Capt Gideon 05-08-2014 07:14 PM

NIJ III+??
 
I have the the Ballistic Resistance of Body Armor NIJ Standard - 0101.06 and I couldn't find a listing for Level III+. Technically there isn't even a Level V, but because of the protection provided of the highest level of Dragon Skin Body Armor the term Level V is applied and the specifications are classified by both DOJ, DOS and DOD. I just kind of guesttimated and could be as much as 4 to 6 points higher.

PS> Level III+ may refer to Level III with Stab Protection, So its Level III Ballistic Plus whatever rating of stab protection, normally Level I.

I've looked around for it as well. I see it referenced by a few manufactures, but don't see it in the NIJ standards either. I think it is NIJ III + AK47 resistant, but not completely sure.

I thought Dragon Skin was no longer made? And NIJ had withheld there certification of it as well.

Capt Gideon 05-12-2014 08:50 AM

Pinnacle Armor
 
Pinnacle Armor, the maker of Dragon Skin body armor, is still around as far as I have been able to find they are still making the armor along with other products. As of 2007 the Level III armor had NIJ certification of the 6 year operational life and the SOV-4000 (Level V) is made but is restricted to sale to government agencies only. SOV-2000 (Level III) and the SOV-3000 (Level IV).

Is there a version with the Explosives listed in alphabetical or grouped by type?

Also can A5 (98.5 to 99% RDX) be added?

I am enjoying this discussion, but I do have a question. I was just comparing dpw numbers from the rules versus the calculation given here. There are some fairly large discrepancies. There are a few that I find perplexing and wonder if there is a reason. Take for example a TOW missile. It has about 3kg of LX-14, which is 95.5% HDX. Using the RE of 1.28, we get dpw of 8867 using the calculation. The rules show a dpw of 3120. My question is, would the fact that the warhead is a shaped charge inside a titanium form to direct the charge forward be the reason the dpw is lower? In my mind, that sort of makes sense, but does make dpw calculation just that much more complicated.

The data was classified in the 1970s when third edition was written..... These days the warhead data is much more public. The U.S. arms industries relies heavily on foreign sales to make U.S. equipment and R&D for future equipment so this is disclosed at arms expos.

LX-14 is used in the later models of TOW, the BGM-71A/B (which is most likely what is depicted in the game book) used 2Kg of Octol which is 1.16 which gives you 5357 Dpw, still doesn't come close to the published number, but I would guess based on the time frame the correct information would have been difficult to find based on the bibliography listed.

As you ask does the shaped charge account for the reduced Dpw, most likely this could answer that question.

According to wikipedia it is the French name for Amatol with a formula heavy on the ammonium nitrate (7 to 1) and with dinitronaphthalene (DNN) replacing TNT.

Looking at the chart above with .32 for pure AN and .68 for a 50/50 mix with TNT (stronger than DNN i believe), I don't think you would get much past .40 but that is really a guess.

https://books.google.com/books?id=u2...losive&f=false confirms the wiki ratios and ingredients.

It looks like the name went out of favor right after WWI as all published references I can find are before 1917.

Thanks....... For some reason the Defense Intelligence Agency is still using this.......Likely a lazy researcher using direct translations from Soviet manuals. No effort to confirm or use modern terminology. Then again...... Soviet manual and archaic terms are a waltz to the numbers.

To good not to share..... Rounds from 40mm and up. NATO and Soviet... by caliber, what weapon system, explosive filler, and amount.

Happy factoring! Attachment 3514
