There seems to be some sarcasm on all the war and military stuff, for soldiers of the invasion side are basically the same thing as marines in-game, not knowing what or why they are fighting for, losing their lives for nothing and so. Most of the marines died because the player is in the mood of collecting Xenon ship models for no particular reasons other than retaliation, an achievement, or a sense of achievement. Basically the nature of human war history from country leaders' perspective, at least the majority part of.
I may be overthinking, but given that this is a German game, it's quite understandable to have some deep reflection on the nature of an invasion. I myself am not in support of any invasion, but I respect the fact wars and competitions facilitated science development on large scales in the perspective of history. Without life hanging on a string, people just don't work as hard in a peaceful world. Make no mistake, this is not a compliment of war or invasion in any sense. It's just I feel the devs may be just a little too critical on all the war stuff.
