The only snag is if you jump from 3D to tactical and back to 3D the vehicle you're in will be stopped, and getting your speed up again each time is a pain. The tactical map can be zoomed in and out, and you can give orders while paused. You can group-select units. In the campaign games, where you play as a corporal and rise through the ranks, control is a problem because it's not obvious which units are under your command - command lines show who is under the command of who, but some sort of highlighting option to make it clearer is sorely missing. Combined arms plays a significant part.
Infantry are weak in the open and stronger in woods or towns.
APCs can be used to move troops quickly, but are obviously vulnerable to tanks. There are trucks that can carry out repairs and ambulances to heal the wounded or take prisoners. The variation in units is OK, but nothing like as wide as in Steel Panthers . And of course there's stock infantry. Snow, rain, woods, roads, buildings, bridges, rivers, rail tracks and trains, rough ground, marshes, etc are all featured.
