Drones

The scuttling swarms of heat rays and slicing tentacles

While the prey creature warriors cannot hope to stand up to the great fighting machines in open battle, they have swiftly learned to use terrain and subterfuge to cause huge amounts of damage to the machines of the invasion force. They will hide in burrows or structures or trees where the heat rays cannot dig them out and wait for the Fighting machines to get close before scurrying out to throw their bombs at close range. The Colonial Conclave on the home-world took in the varied reports of the prey creatures actions and some of the finest engineers of the race came together and devised a machine to dig the prey out of their holes. When the third wave of reinforcements landed on the target world they brought with them plans for these "Drone Machines" as well as a number of working models.

The drone machines are not fully autonomous and therefore cannot operate without a being controlling them from their tripods. This being directs the machines around the battlefield and dedicates targets for them, where the limited self control will then take over in an attempt to destroy the target. The drone machines have proved themselves highly effective against the dug in prey creature warriors, burning them with their miniature heat rays and dismembering them with their small reaper blades. In large numbers, they can even bring down the armored projectile thrower vehicles which have proved so troublesome.

In All Quiet on the Martian Front

The drones are an interesting unit to compliment your force of large, somewhat unwieldy war walkers.
