Overall, I like the new mercenary book. I would have liked an example mass combat though, walking through the process step by step, to make it easier to understand. Since the new mass combat is based on regular small-scale combat, and appears to be designed to be simple to use, this isn't that big an issue though.
Layout and design is very clean and easy to follow. The new take on gun combat skills and AP, destructive and such are, as seen here on the board in previews and playtests, streamlined and improved.
I like the option of pre-career education.
One thing I dislike is that the 'tickets and missions' chapter comes between 'force organization' and 'battles and wars'. I feel the latter two should have been directly after one another, since there is a natural progression from creating units to fighting battles, and annoying to have to flick through an additional 15 pages to continue.
I was surprised at first to see that blast radius isn't taken in account in mass combat, but soon realized that it isn't needed, since every point of damage is one enemy taken out and blast weapons tend to roll many damage dice - nice, quick and simple!
The new conversion between ship and personal weapons is another thing I like. Sure, it makes ships weaker compared to vehicles and infantry, but it also stops invincible fighters from defeating entire squadrons of enemy vehicles. Most of all it gives the game a better flow.
With the new rules for destructive weapons, burst-fire looks more attractive. (1d6+4)x10 is a lot better than 10d6+4.
When it comes to destructive weapons, I can understand an auto value of 2 (the first model of PGMP) since the damage multiplies, but there are a couple other weapons in the list with auto 1 or 2, and I don't quite understand how they're supposed to work...?
Question: it seems DD in itself does nothing with regards to armor piercing, meaning that ship weapons are in some cases weaker than vehicle (or infantry (PGMP, FGMP)) based weapons, is this intentional or just a placeholder until the next high guard? A PGMP with ap 30 is more destructive than a ship-based beam laser, for instance.
Also, has flechette ammo lost its AoE?
All in all, great job!
