I don't see such a "need".
This is what I like to call "Jan Mayen Syndrome". It's a non-issue that everyone has an opinion on, because it's suddenly being talked about, but nobody actually has a big problem with... and, because it's being talked about and they think it's easy to fix, they think it should be addressed straightaway.
It is an easy thing to change... but, honestly, who cares? Changing the name will just cause the same people who couldn't tell what "Guards" are in APD by looking at the stats to asking what "Motorised Infantry" is because they've never seen it before.
