Tank 432 (originally Belly of the Bulldog) is a 2015 British psychological horror film written and directed by Nick Gillespie. Gillespie had previously collaborated with Ben Wheatley, who executive produced. Rupert Evans, Deirdre Mullins, Steve Garry, Michael Smiley, April Pearson, and Gordon Kennedy, Tom Meeten, and Alex March star. Evans, Mullins, Garry, Smiley, Kennedy, Meeten portray mercenaries tasked with transporting a hostage (Pearson) and survivor (March) across a battlefield. Along the way, the mercenaries become trapped in an abandoned armoured personnel carrier they enter as refuge against an unseen enemy. (Despite the film's title, the vehicle portrayed is not a tank but a Type 432 armoured personnel carrier, a vehicle used to deploy infantry. The 432 was known in British Army service as the Bulldog, hence the two alternative film titles.) It premiered at the Fantasia International Film Festival.

Plot

In a forest, mercenaries Reeves and Karlsson rejoin the rest of their squad – Gantz, Capper, Evans, commanding officer Smith, along with two hooded and bound captives. Reeves reports fleeing from a group of hostiles, as Karlsson sedates Capper, whose leg is badly wounded. Evans reports a farm and jeep nearby, and Smith orders them to investigate. At the farm, Reeves vomits after seeing a mysterious orange powder. Evans, already nervous, becomes increasingly erratic after finding the jeep's engine has been sabotaged in a gruesome manner. As Karlsson sedates Evans and tends to Capper, Reeves and Gantz explore the farm.
