R.E.A.R.M. - "Rearmament Expansion And Redesign Mod" is an unofficial Homeworld 2 expansion and it adds number of new interesting and various units.
Obvious strategic media exposure no. 1:
With a little help of the Reseach Station the Modular Destroyers can build platforms.
Most argue it's a waste of firepower and it is a reasonable concern. But if you want a counter argument, you can miss one destroyer's turret and still exceed in firepower over a regular Destroyer, plus the ability to build a nest of double ion platforms can be seen as a firepower multiplier instead. That or a distraction of incoming fire away from the destroyer and onto the platforms.
Nevertheless it's not at all expected to be widely used, though it's nice that the possibility is there. It's also a little reminder that such thing as a platform even exists (well how many years ago have you built your last weapon platform?).
