* HilariousInHindsight: Rodney Rowland plays a [[PeopleJars vat-grown Marine]] in this show. Several years later, he plays a [[RunningGag series]] of [[CloningBlues cloned]] [[RedShirt Red Shirts]] in ''Film/The6thDay ''.
** One of the rejected nicknames for Chigs in the pilot? [[Series/TheWalkingDead Walkers]].
* NightmareFuel: In one episode, the Chigs are testing a weapon that basically ''weaponizes'' NightmareFuel. It causes your deepest fears to be cranked UpToEleven. The only way the squad is able to escape is by marching in lockstep out of the weapon's area of effect. ''Through a minefield''. It helps them overcome their fears because [[ThePowerOfFriendship they trust each other that much]].
* RetroactiveRecognition: James Morrison, who plays Tyrus Cassius "T. C." [=McQueen=], is likely far more recognizable nowadays as Bill Buchanan of ''TwentyFour'' fame.
* UncannyValley: Between the bits of "skin" that have flaked off from lack of maintenance and the fact that they all have crosshairs in place of ordinary-looking irises and pupils ([[{{FridgeLogic}} even the]] SexBot [[{{Squick}} models]]) the Silicates invoke this trope pretty heavily.
* UnfortunateImplications: Wang is the one Asian guy in the squadron. He is often portrayed as being nervous or afraid, is unable to issue a Marine Corps BattleCry during the pilot episode, and is the guy who gives a false confession while being tortured, and later [[spoiler: collaborates with a group of Silicates and secretly gives them some of his squad's sparse and much-needed equipment in order to prevent the confession from being used against him.]] Joel De La Fuente, the actor who played him, complained about this.
* WhatAnIdiot: The human race. Created a slave race only to have it turn on you? The solution is '''''not''''' to ''create another slave race!'' [[TooDumbToLive Dumbasses.]]
** Also, when an almost unstoppable alien enemy force finally decides to negotiate, you don't get all irrational and emotional, endangering the talks. And you ''especially'' don't allow the negotiator to get killed. Geesh...
*** Even more so when said negotiator outright tells you they know all about your "war ending" battle plan and only enter into talks because it might damage their holy breeding grounds.
