And yeah, I'm burning through soldiers. I actually got a bit lazy with the Thanqol naming too because they were dieing so fast. I knew it was getting bad when the game actually started changing the memorial room graphic to have more pictures on the wall and additional glasses of whiskey shown next to the little monument and there are so many pictures that I can't count them all because they're obscured by the interface. When I finish, I'll post the complete list of the memorial wall so that we can salute the brave ponythreaders that gave their lives (or corporeal vessels in your case) to save the planet from aliens.
The number of results from google isn't reliable. You need to run a tool to get a better number. See this xkcd blog post.
