Incomplete! The TRO 3039 is arguably the best TRO out there, as it covers the succession wars and the time before the clan invasion. Basically everything formally known as Level 1. The record sheets: 3039 however, lack. The description says: "some of those Mechs and verhicles... " SOME. Out of the 84 Mechs in the TRO 3039, only 58 are in this record sheet pack, leaving out important designs, such as the Commando, Clint, Vindicator, Catapult, Awesome, even the Atlas isn't there. And no variants at all. Only 32 out of 45 vehicles. Why didn't they just make a complete collection? I would have payed even more for it.

The way it is now, it does not serve the needs of a serious BT player.

Why would you get this instead of the unabridged version of record sheets 3039? For the opening scenarios and rules prior to the actual record sheets. From what I can see with the other 'abridged' record sheets products, they usually have something from Tactical Operations for people who want to sample some of the advanced rules found there. This particular book actually has rules for using vehicles which complements the introductory rules in the Game of Armored Combat boxset and possibly the standard rules in the Battlemech Manual also. For my friends that I'm introducing BattleTech to, this should actually be a nice addition for mixed vehicle scenarios without introducing any rules complexity. For people with Total Warfare or the unabriged record sheets, this book is pointless so that's why I took off one star. There are record sheets missing from this book that can be downloaded from Catalyst's website here which will give you the complete list of standard variants of battlemechs. You can find that here:

Here's where the classics mechs are. Well put together. These are the ones I remember using 30 years ago and the ones I'd like to play now.
