+1 for the addition of medics. but i don't think you can remove the Officer Job as i think its a default for all battalions.
-1 on the Purge additions. The purge weapons surpass the Westar in terms of usefulness and strength. Not to mention both are currently Perma weapons purchasable through credits, which i don't think the Developers or Founders want to circumvent by giving to a Subunit.
