They're too rare to occur in the kind of battles represented in this game. For example, even one of the most unreliable tanks ever built, the British WWII Crusader, suffered one breakdown every ten miles. Most SPBMT battles are about 2 miles wide. So if you buy ten Crusaders and run them across the average MBT map, two will break down. Most tanks take 12 hours or so between breakdowns, and helo failures are much more rare, so it would really only matter for VERY unrelaible and poorly maintained vehicles. Don't get me wrong, their are some like the Russian ZSU-57 that can't go farther than 20 miles without falling apart. If breakdowns were a significant factor, then I'd support including them. But there are probably more important things that take priority when it comes to adding features and program coding.
