I appreciate that this must be a simple question, but it's been ages since I last played the game, and now that I'm playing again with friends I feel quite rusty. If my units are advancing from A to B, and the enemy's units are advancing from B to A, and they run into each other midway, who's attacking and who's defending? I wanted to know, because obviously with units like tanks it makes a big difference whether they're on the offensive or not. Thanks!
