While we are at it. Couldn't the Strategic Bombing mission changed so that it damages forts? It would be nice to have some way of hurting those nasty bunkers!
Nah, I'd group that under installation strike, if anything...after all the Strategic Attack mission is fairly straightforward in purpose and effect.
Plus the same review of "history" informs us that while not totally ineffective, the extensive bombing and shelling of fortifications don't have as great as effect as one would like and on top of that churn up the terrain and whatnot so as to make the inevitable infantry advance against those positions as that much more difficult and less likely to be supportable by armor.
What bombing and shelling fortified positions does do is kill men on an incidental basis, and if done for a prolonged period of time (a couple weeks) can reduce morale/org.
