Your spirit animal is a honey badger? That's nice. My spirit animal is Sigourney Weaver in a jumpsuit unleashing a plume of hot death over what looks like a dry, potentially disastrous, patch of grass.

Xenopedia, the AvP Wiki, has a wonderfully informative entry on the "M240 Incinerator Unit," and the backstory on this photo:

The large raised section on the front of the Flame Thrower is the result of a large (compared to modern lighters) electronic gas lighter with a U2 battery (more commonly known as a D battery) being used to create the pilot light. A remote switch was used to turn on the lighter inside the Flame Thrower. Once the Flame Thrower was lit, director Ridley Scott "liked to keep it that way".

At least Sigourney Weaver (Ripley) test-fired the Flame Thrower (presumably before using it on set) on the lawn at Shepperton Studios' backlot [To be clear, that's what's going on in the photo up top – Ed.].

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.

Some shots of Weaver wielding the weapon in the film, for good measure:
