Bought mid-battle with supply. Each one gives something and costs something.
No single hit can strip more than 30% of maximum hull after shields. Mobile units lose 12% thrust; static emplacements lose 18% maximum integrity. Strong into alpha strikes, weak into rapid fire.
Burns at +65% speed while marching or closing on its chosen standoff, then disengages in combat; turn authority is halved during the burn.
Converts the squad into a breacher: it closes to 45% range and deals +60% damage there, but deals 15% less outside the breach band.
Creates a 13 km blast core and wide falloff ring, but loses friendly-fire safeguards.
Mine enters a phased sprint while out of combat; firing collapses the protection until it disengages.
Mine may deploy from either flank strip and accelerates into the opening breach.
Mine exposes cloaked contacts and marks targets for nearby allied fire.
Mine detonates across a wider falloff ring that can also catch nearby allies.
Mine fields 40% more bodies, trading individual armor and weapon output for saturation.
Mine ignores light screens and drives its contact charge toward capital targets.
Mine scatters autonomous interceptors that screen its formation from guided ordnance.
