"Checking for lifesigns?" Martha asked. Well, it's what she would do. Or alien tech, or...well, there were a number of things. She reached down and picked up a broken chair leg from where it had been discarded on the ground.

"I've seen the Weevils back in Cardiff. Terrifying things, all twisted and mutated faces." And she doubted her ability with a chair leg, but it was probably better than the Doctor with the sonic screwdriver. Most of her other UNIT crew had a gun, but Martha didn't want one. Guns were only good for killing. The chair leg, at least, could subdue and keep whatever was hurting the screaming person alive.
