@Salrantol are you doing C:SM now? There's a lot of places where you can trim up the fat in it. All of these duplicates here are entered as Aux, Formation, and sometimes Core as well. Add them to Shared Entries and just link to them.
There's also multiple entries that all reference the same vehicle/unit/whatever, but all have their own entries for them nested in rather than link to a shared entry.
If we try to convert those entries into a shared entry, we get this completely superfluous nesting (because there's the Auxiliary or Formation you select, and then the one it links to). Is this preferable to a slightly larger file?
