Yes on that one. Being able to spend resources to give xenos miletary gear is a huge plus.
Only problem is chems work for xenos on toucch not injection. So that would need to be a very fancy acid vest.
Sadly spray bottles are super inefficient at delivering units of chems… i not sure of the exact ratio but i willing to bet its some where around 10 to 1 so 10 units sprayed for 1 unit put on. Smoke workers much better.
