This is the Harbinger, a VTOL intended to bolster mercenary units working the Periphery while regular army units are being moved towards expected hot spots in the Federated Commonwealth of 3063.
Unfortunately, this is part of a package - a tank, a 'Mech and a VTOL - that was nixed by the politically unreliable nature of mercs in general. The Harbinger was the only one to see production.
It carries three machine guns, three SRM-6s and a mast-mounted Beagle Active Probe on a 30-ton chassis which moves 8/12 and carries about two and a half tons of ferro armor. Excellent for anti-personnel ops, there is only a single ton of ammo for each weapon type, precluding extended engagements.
