!In Ground Control
* GameBreaker: Artillery cannons have a very long range, way beyond harm's way and are insanely powerful. The only thing they need is anti-air support.
* MoralEventHorizon: Major Thomas destroying the medical facility whose occupants already waved a white flag at the beginning of battle.
!In Ground Control II
* BreatherLevel: Missions 21 and 22 introduce the final arc of the game.
* MostAnnoyingSound: Your units have a habit of announcing every single instance of damage they take. And then there's "We're losing a victory location! We've lost a victory location!"
* ThatOneLevel: Several missions stand out as being harder than the others. Missions 23 and 24 are particularly murderous.
