I've actually lost a battle against the GH in Kiev when they managed to charge MHC across right at the moment when just about all my pavs arbs where out of ammo and halfway across the map withdrawing.

my halbs were also decimated form earlier waves and at 2 energy bars.

they timed their charge with mongol warriors focus firing on my halbs so my plug routed and a unit of MHC got across before I resumed the plug and that replacement halb got overrun in the rear with my general not enough to stop the MHC.

lost the bridge and lost that battle.

such horrible timing, GAH
