In an article by Chris Lawrence in the V1N5 newsletter ("The Second test of the TNDM......", pg 40-50), TDI examined the battalion level database.

It was found that for battles <24 hours, the predicted casualties were too low. A couple of changes were tried, and if I read the article correctly, consist of the following:

1) battles less than 4 hours are treated as 4 hours
2) battles less than 24 hours have casualties = SQRT(fraction of 24 hours) as opposed to (fraction of 24 hours)
3) fanatic combat results in casualty rates 250% of normal

Reading through the article, I wasnt sure if #2 was still in the mix, or was it thrown out by the end of the article ?

thanks,

#2 is not in the mix. The revision we made to the TNDM incorporated #1 and #3 in it. Glad to know that someone is reading my stuff!

So, as long as the combat time is >4 hours, battles < 24 hours have linear fractional losses (8 hour battle = 1/3 losses) ?

I grabbed all the newsletters and started digesting them, looking for relevant information.

Do you guys sell the different databases separate from the TNDM contracts ?

thanks,

Yea, it is an uncomfortable modeling compromise, but it seems to work. The main problem is that a lot of battles have a short intense period amid lots of less intense periods, so by running the models in really short time increments, it distorts the results.

I can email you the latest two newsletters. We have not updated this site since 2002.

Yes, but at prices for large organizations. It is out of reach for individuals. Some of these databases have hundreds of man-hours of labor invested in them. For example, our division-level data base has more than 740 cases in it now. If one figures that it takes and average of 3 days to create a case, then were are looking at something like 9 man-years invested in creating that data base.

I have Vol 1 #1-6, Vol 2, # 1-4 and volume 3, #1. If you have any others, I would love to get them.

thanks,
