From a personal standpoint, for my style of gaming, the rules themselves might be slightly much to handle alone. However, objectively, they're well written and pretty concise as far as miniatures rules go. The core rules aren't the reason I gave it a 4; the main reason is the lack of a bookmark sidebar, which would be extremely helpful in referencing certain nuances mid-game.
From a more biased standpoint, I'd like to note that once again, Nordic Weasel Games has delivered a rather useful tool within a game that, even though I may not end up getting much use out of the core book, will be extremely helpful to me in other endeavors. In this case I refer to the solo play rules and the tables occupying the last third or so of the PDF.
There are comprehensive rollable tables for campaign attributes such as random forces (WW2, Modern, Irregular, Gang and SWAT), fireteam generation, vehicle presence, a war generator for both earth and spacefaring settings, and even some goodies in character creation that help you define the background and personality of a character you don't already have down in your head.
Perhaps most intriguingly, the campaign rules give you rules and rollable tables for such things as the nature of injuries that befall those taken out in combat (from light wounds and dramatic scars to permanent injuries and death), replacements and recruits, campaign events (reassignment of soldiers, arrival of a new recruit, and so on), and of course, full-on mission generation.
For me, the strength of Nordic Weasel titles has always been the robust random generation, and these are things I feel like I could transplant into any game. In fact... I was going to give it a 4 for the lack of a bookmark index, but the more I look over these bonuses at the end of the book, the better I feel about this purchase. Five stars, for depth of utility alone!
Short Version: (And mind, this is from a very individualized standpoint.) If you've been searching for a game that lets you take control of a squad or platoon and follow them throughout a procedural military campaign, as I so long have, this is your train. Get on and ride this baby to glory. (Or... horrific defeat, as circumstances may dictate. May the dice treat your boys well!)
