Book Review – Raising Steam by Terry Pratchett
Raising Steam by Terry Pratchett My rating: 4 of 5 stars To begin with I was worried that Pterry had lost his touch. This book is somewhat different to the earlier discworld stories in that it lacks a geographic focus, however once I got into it I realised that this was because the coming of the railway means that the world is so much smaller. The focus in this book isn't a handful of characters in a limited environment, but the handful of characters spread all over the area covered by the trains. The introduction of steam to the discworld gives it a very 19th century feel. Somehow this does it in a way that the clacks didn't. The main protagonist is Moist von Lipwig but Vetinari, Vimes and the Watch feature as support along with dwarves and goblins. Unusually…
The Stress of Battle 5 – WW2 Heroism & Surprise
This is the fifth and final part of my extended review of The Stress of Battle by David Rowland. It is such a strong piece of operational research that I thought that it would be useful for wargame designers (and players) to understand what the research evidence is for what went on in WW2 battles. This part is on the effects of heroism and combat degradation. Combat Degradation Combat degradation is a measure of how less effective weapon systems and individual soldiers are in actual combat when compared to training exercises and range work. A score of is equivalent to not being degraded at all. Degradation to would mean that it was operating at 30% of its peacetime range effectiveness. the analysis by Rowland's team broadly matches that done by Wigram in 1943, that there are three classes of effectiveness. About 20% of those involved could…

And a bit of viewing too! Got quite a few things from my wish list that will help me with my next writing project.
The Stress of Battle – Part 4 – Op Research on Anti-Tank Combat
This is the fourth part of my review of The stress of battle: quantifying human performance in combat by David Rowland, which is an essential piece of Operational Research on WW2 and Cold War combat operations. Unlike small arms, the effectiveness of anti-armour weapons has changed considerably over the course of the mid-20th century. From non-specialist gunfire in WW1, to high velocity armour piercing in WW2 and then to Anti-Tank Guided Weapons in the Cold War period. This makes the operational research harder to do because the start point needs to be battles where only one kind of AT weapon is in action. Much of the analysis starts with the 'Snipe' action during the second battle of El Alamein in North Africa where data on each of the guns individually was available. 'heroic performance' plays a large factor in the effectiveness of anti-tank guns about a quarter of guns (at…
