The sound of engines drifted on the wind. With squealing tyres, a trio of groundcars came tearing around the corner of a ruined building. Each one had six wheels and no roof. They were packed with men in uniforms the colour of faded sandstone, with dark blue piping along the seams of their trousers. Their boots and armour were scuffed and weathered. The majority of their weapons appeared to be large-calibre projectile rifles, but Chavis counted at least three serviceable-looking grenade launchers. None of them wore any kind of hat or helmet. Their hands and faces were sunburnt and blistered, and each of them looked as if it had been months since their last good meal.
'Autonomous fire sanctioned!' Chavis yelled.
The groundcars spun wildly, and the men aboard them opened fire. Bullets ricocheted off piles of rock and the armour of the Scions.
...
The soldiers in the other two vehicles sprayed the Scions with bullets. Savdra and Brandt killed two of them for their efforts.
