It's not about them being defined. It's about gameplay. That's why I pointed to Battlecruiser - the IFF and CSP and FTL and PDD and whatnot are just too annoying. They're all in the manual, but you can't keep track of them all the same.
But where do they come from.
If these are technical terms (and not siome acronyms invented by the designers) i can identify at least two of them from memory because they are _very_ common like IFF (identification friend foe) and FTL (faster than light travel) which we btw already use in the techtree and storyline somewhere
The point is that I don't want to spam the player with technical explanations and terminology - in short, an interesting lie is better than a dull truth.
Gimme a good term for the weapon platforms and we'll stick to them. If possible not 'tank', that's even more irritating than an acronym if you ask me.
We could even leave the second term out and just call them "Triax" and "Phoenix" ... even shorter and players will have no problems memorizing/identifying them.
By the same token, don't copy too much from wikipedia into the UFOpaedia - it's a good explanation of things, but it's not a fun read.
I took exactly two sentences (that were heaviely modified by me to make them more player-friendly) from wikipedia [1]. The rest of the links i just provided as reference for others. No word copied for these, everything new.
Laser is kind of an exception; it's used as a word, not an acronym. Some acronyms are like that (AWACS, NASA, Modem, etc).
No, the are no exception, the are still used as acronyms, but since they are more popular and most people do not _know_ the real meaning of the words and that they are acronyms. But that's just a matter of definition
