Notice the server for today's game is different than prior campaign matches; it's the same as for the Event last Saturday.
It is the new WaW 100-player server at 209.222.20.118
For the planned map today, Invasion of the Philippines, the changes I could see by looking at differences in the files are as follows; not all so minor, actually:
* JP get the kneemortar infantry spawn kit instead of turtlemine kit.
* US gets satchel infantry spawn instead of comp b.
* US gets Fletcher changed to a reinforcement, (get it when Allies bleed).
* JP gets antitank infantry spawn kit, (this compliments what the US already had, the tankhunter).
* Ship supply/repair static put in.
* Airfield get supply/repair static.
* JP pickup sniper kit fixed.
* US gets hellcat instead of wildcat.
* Flag cap time reduced, (from 60 sec for each getting and losing control phases to 45 sec each)
There could always be server-side changes, too. But those are rare and usually just for critical errors. I haven't seen any need for that... at this point.
