"And I tell you it was the biggest, hairiest spider I've ever seen - and it was RIGHT THERE!" Tank girls ready their equipment for a desert exercise. Even in their high-tech skinsuits, they'll want the cooling system to be running perfectly. Then the anti-grav has to get them to the target-zone and (more importantly) back again. When they reach the targets, it will be useful if the cannon is working properly, of course. But never mind all that. Sergeant Hunter hates spiders and she is not crossing all that desert knowing that she is sharing the tank with one. Fortunately, she can pull rank on Private McCaffrey, to do a spot of pest control.
