As Imp and Gila noted, this is not terribly challenging but it's lots of fun. Objectives are spread out along both sides of the river and you have to decide where to commit your forces in the best proportion. There are plenty of tanks, cavalry and marines to spice the action.
Sad to say I could only manage a marginal (score was 2300-something to 411). Couldn't reach the last westernmost 50-pointer in the river and had to give up another one after the river's second bend in order to save the two at its first, owing to a vigorous partisan "surge." Plus the Yugo HQ managed to hide after getting routed, cheating me out of 50 more. All in all a well-crafted lolapalooza
