Hello,
There have been some variances in the stats of the creatures presented in prior Handbooks to A Time of War rules. Many of these are an effect of game balancing, however, making their changes more arbitrary. Fortunately, because the A Time of War system derives so closely from MechWarrior 3rd Edition (CBT: RPG), conversion is otherwise a fairly direct effort, largely involving "delete the 'D6'"
Hopefully, that helps.
Thank you,
