Sahharran Ground Assault Drone

"They came out of nowhere. One minute the AT-ST's in our support squadron had guns blazing and we were advancing at quite a rapid pace, and the next all of the AT-ST's were minus one leg and our platoon had been transformed into a squad. -Unknown Imperial stormtrooper"

The Sahharran D-90 Ground Assault Drone was a droid designed to combat the threat of the Imperial AT-AT, as well as turrets, large groups of infantry, and tanks.

Details
The D-90 Ground Assault Drone is a sleek, remote-controlled drone with a shape similar to that of the TIE Defender. It carries two light proton cannons fed by magazines concealed in the body of the droid, which is covered on all surfaces by 5 cm thick Kevala plating. These cannons can slip through any shield, and have enough power to punch through AT-AT armor. Since the drone is remote-controlled it is equipped with infrared scanners and target recognition software that assists its controller with target acquisition.

History
The first idea for the Sahharran D-90 Ground Assault Drone was presented when a Sahharran Elite Agent inserted into the garrison of a supposedly unimportant Imperial base witnessed the testing of a prototype for a new Imperial walker. The sheer power of the new design shocked the agent and he immediately reported his findings to the Sahharran Military High Command. The High Command soon recruited Aries Fleet Systems to design an attack craft to combat the new threat. The result was the FB-2 Hawk fighter-bomber. However, the estimated time required to complete the design, iron out all of the many persistent bugs, and get the aircraft into production, as well as the time needed to complete the Sahharran Navy's requirement for 40 squadrons of 5 aircraft was nearly a year from the current date. The High Command knew that this was not soon enough. Although the FB-2 project was allowed to continue, the High Command knew they had to have a ground attack craft as soon as possible, so in desperation they turned to Gemini Droid Technologies, designer of the remarkably successful D-7 Sentry Drone, to design a ground assault drone for use by the Sahharran Army. The result was the D-90. In its first combat sortie, defending the Sahharran outpost on Treklon, the D-90 showed its prowess in the anti-vehicle role, with one training squadron of 5 aircraft destroying 20 out of 25 AT-ST's sent to support the infantry force, which also suffered incredible losses at the hands of the D-90s. Throughout the D-90s service life, which still has not been terminated, it has performed excellently in the ground assault and anti-vehicle roles.
