If there's an attack on wilycorp, we should ask light to grab any computers or tech they can, so we can reverse engineer it and get any security codes we can from it.
If lights forces can disable the teleport interdictors in wilycorp we could send in a squad to smash and grab whatever looks valuable.
From what i remember xenomorphs navigate by sonar, let's jam that to disorientate them, maybe also neutralize the acid with a weak alkaline, like baking soda (Only if we can vent the air, xenomorph acid reactions might give off fumes) (To get such a chemical, either transfiguration or scan for chemical plants, then locate suitable chemicals)
If available, teleport support could build cover for our troops, close gaps like the one the xenomorphs made, and remove harmful substances like xenomorphs, xenomorph acid, poison gas, guards, ect by not rematerializing the target, or teleporting slices of the target into a containment bay or just into the ocean.
Also, aurors can do some of those things too
