@Alex Hart and the rest of the gang, I just want to clarify some things since this was totally not planned.
First, they are only attacking military installations. No civilian buildings.
Second, they are seeking to force a surrender, not dominion.
Third, and this one is totally my fault, they are not firing positron(antimatter) shells from space. They are just firing Armor Piercing High Explosive shells. Big howitzer shells.
And lastly, this is in response to multiple items. Keller threatening to incarcerate Alex, who is serving as an envoy of the USO, invoked the wrath of Uso who said she'd nuke the city.
Mr. Donovan, who takes her very seriously, is launching this attack to force a surrender and meeting with the city's leaders(which he doesn't identify as the mecha pilots). And frankly he did say that bad things would happen if they tried taking Alex so hopefully next time Mr. Donovan puts his foot down about not taking/harming his people, friends, and allies they'll take him more seriously. I mean, he's a robot. As far as I'm aware they don't bluff.
EDIT: I got of topic

Basically he's attacking so they don't get nuked.
