I was just pondering what strategic aspect was missing from HOI, and bridges came into mind. Rivers have no strategic importance, other than as a good natural defense. It seems Bridges is what has been forgotten in all of this.
Perhaps river crossing brigades of sort, primarily consisting of rafts are required to be attached to a division to cross a river, without a bridge. Engineers are capable of destroying them, given adequate time. So infantry can cross, but a type of portable bridge should be able to be created by engineers in a few weeks time, for the crossing of armored divisions. Of course, a modern bridge should give no or little movement penalty, while a portable should require a significant one. Something that would definately make bridges a key aspect and possibly a serious of bottlenecks, requiring suprise to capture and get across them, which we've seen historically.
Unless something like this exists, it's to late now, but something to consider in the future.
