-1 The limitation for job slots is artificial and could just be increased rather than remove something from the server. With the move away from the F4 menu standard to DarkRP (base for most Star Wars RP), and the eventual move to Helix (I believe) it doesn't really matter how many jobs are in a battalion as there isn't a massive menu to clutter up in F4. It doesn't really matter how large a jobs.lua file is either so long as it is sorted nicely by the developers using it. Why not just suggest increasing the number of allowed jobs rather than take one away, or just allow each Battalion's Commanders to make such a decision regarding jobs within their Battalion? If they want an extra thing added and have something in mind, increase the "job slots" and allow them to make a suggestion for it rather than remove Officer while they might have nothing prepared. It's already a struggle enough to make jobs unique and have a draw to them, most battalions may struggle with trying to fill an extra job with players, unique weaponry, and a unique RP position on the server.
Regarding freeing up the weaponry on the job to be added to other things, it's not like it is not allowed to put the DP-24 on other jobs and like it is ONLY possible to be used by officers. Furthermore, it will be kind of lame to get rid of the job and have Commanders (non-lore) be unable to use Dual DC17s since they'd be forced to use the Trooper job and just use the standard weaponry for a Trooper. If you're a Commander you shouldn't need to play on a Regiment whitelist to get additional weapons, especially those that were common in lore for Commanders and Officers to use.
There are other guns that Heavy and those other jobs could use anyways, such as the rw_sw_dc15le_o, rw_sw_dlt19s, or other more unique weapons that could be added.
