I have mixed feelings about FiveCore Brigade Commander.
In many ways, I like it a LOT. The "fire for effect" mechanic which is also used in Five Core Company commander is very different than many wargames.
You roll "kill dice" and "shock dice" in combat. The better your unit, the more dice you throw. The results can remove the stand from play, or degrade it's ability to move and fire or paralyze it. Retreats are also possible.
There are many different troop types, and these,in my opinion, model reaistically their real world behavior.
Tanks are handled as "similar, better, worse, hopeless" in term of technology difference. People who like to count mm or armor and such may not like this approach. BUT it does reflect how real commanders think, and more importantly how a commander would fight his unit.
About half the rules are devoted to creating scenarios, campaign generation, and other variations.
I think what I dislike is that morale is built into the fire combat shock and dice rolls. I also dislike the HQ is essentially nothing but a target.
However, I DO like the 5 Core Company Commander a LOT. It is very similar to Brigade Commander.
I am not at all sorry I purchased it, and likely will play it again.
