Not a bad idea. I think YA'LL gettin carried away with it though.
Troops as it is have a singular mission get to the map room. If you change that mission then troops that should be running for the map room might go somewhere you didnt want them to. And this is beside all of the additional cpu usage required to complicate the "singular mission."
I think to make this feasible and in the realm of Hitechs consideration it would have to be simple. Troops would do exactly as they've always done and run straight for the map room. When they pass by an object within 20 yards that object is destroyed, no re-animation required. The amount of damage would have a fixed value just as suggested already.
If you wanted a mass assault on the base with troops, you would have to drop them at multiple locations around the town so that they are passing through as many parts of the town as possible on the way to the map room. But they will unlikely pass every object in town leaving some work to be done by players.
But if what I saw earlier in this post is correct and HT is considering a FPS, this is all in vein because you will soon need to grab your M1 Garand to take a base.
I understand what you are saying but it isn't necessary. Right now you can't take a town without everything being down anyway so if you dropped the "new" troops early, they would just go to what object isn't down. Either way, you would have to drop more troops. Again, a massive air drop would be in harms way with Ack, fighters over town, GVs roaming to town (a tank firing HE rounds into town would kill a ton of troops with a 500ft blast diameter). Again, if you limit the number of troops that are deployable at each base, D-Day style assaults are not possible and it would add a little fun and another option.
