Sigourney Weaver With A Flamethrower

The Alien movies have a lot of bad ass scenes where Sigourney Weaver carries around a flamethrower like a boss.

Here she is testing it out for one of the first times.

The Alien wiki site Xenopedia has a write-up on flame throwers throughout the series:

The use of the Flame Thrower in Alien began something of a tradition in the Alien franchise of flamethrower weaponry featuring in the films — Aliens would prominently feature the M240 Incinerator Unit, Alien Resurrection would feature the Draco Double Burner and Prometheus would also feature a flamethrower. Despite not featuring flamethrowers, the prisoners in Alien3 also used fire as a weapon against the Dragon.
