Meanwhile, a team of 6 XV15 Stealthsuits shadowing the Chaos force the entire time launches its attack. These Stealthsuits had been deployed on Fokelike years before, and had monitored the city goings for the Tau forces continuously the whole time. Once they had heard of the Chaos and Imperial forces converging on the planet, they intercepted many of the transmissions and tracked each force, silently followng and not intervening until necessary.

Several Alpha Leigionaires are slain, but the fusillade of Burst Cannon fire causes the group to seek out cover. As the other Stealthsuits provide covering fire, the Shas'vre readies his Fusion Blaster and fires upon the large object the team is carrying. A huge bang occurs, and the device disappears under a cloud of smoke. As soon as the elaborately dressed marine comes out for vengeance,  the Stealthsuit team throws down a series of Photon Grenades, blinding and deafening everyone nearby. By the time everyone gets their vision and hearing back, the Stealthsuits are gone.

If the thing had a rare power supply of some sort, the Stealthsuits merely destroyed that. If not, they took out something that needs to be replaced before the device can be used. I'll leave the exact effects of the attack up to you, seeing as I don't know what the thing is.
