There’s a difference between heroes and leaders. At least, there is some of the time. A few individuals can do both, but many of the heroic survivors of Greenville’s largely disintegrated population aren’t cut out to lead troops in battle. They have other qualities that come into their own under different circumstances and will leave the leading to the army guys.
For the moment though, I just thought I’d mention the military leaders and their signature trick, which is to activate several of their men at once. This allows the leader to make coordinated attacks (or “advances to the rear”) at critical moments in order to overwhelm and surprise the opposition. Normally the turn sequence limits a player to moving two models at a time, but this allows a leader to move himself and then up to four more nearby soldiers. With this ability the military heroes work very nicely with hordes of soldiers around them, which makes sense visually too.
Sergeant level characters now have the ability to do this same trick, but only once per game (rather than with “Hero Points”). This makes waiting for the right moment even more important for them, though it does take a bit of the pressure off your heroes and means that the influence can be spread more widely. The range on this effect is quite short and having several models that can do this allows you to keep your opponent guessing about where the axe might fall.
Of course, on a multi-mat battle this is even more useful. With more troops you’ll want ways to move them around more quickly, and this is just the ticket.
