Honestly abbreviations should not be in the name of the article for a 'main' object. THe main object should be fully named, unlesss like
@Wes said uncomfortably long. However I also think accessories or sub articles tot eh main object should be allowed to use the abbreviation in it's name. Also
@HarperMadi things like the M4 are not really an abbreviation, but 'product nomenclature' which is different.
@FrostJaeger what you put is product nomenclature too. It's less 'abbreviation' and more 'designation' and primarily designed for cataloguing not for human recognition.
Abreviations are things like LASR and LNC. These shouldn't really be in titles, if you want to make a fancy acronym that spells out a word, just make that the official product name and make a note that the name was derived from the acronym during development.
This doesn't mean Abbreviations and Acronyms shouldn't be used, but putting them in the title just makes it difficult for people to search for the product unless they're familiar with it, cause abbreviations and acronyms don't tell you anything. Same with if you only list product nomenclature without basic descriptors of the item. No one knows what a Na-C3-E3104 is unless they are very familiar with the system.
Example, LASR, fires -solid- munition. So if you as a new player were looking for "that assault rifle that MINDY pilots use that fires bullets" you would never think to look for 'LASR' which is clearly readable as 'laser'.
In short the rules about no abbreviations and acronyms are about making it easy for people unfamiliar with a product to find it easier. You can always do it like the
LNC article title though is you really want to.
