Those Dirty Dogs (Italian: Campa carogna... la taglia cresce, Spanish: Los cuatro de Fort Apache, also known as Charge!)

is a 1973 Italian-Spanish Spaghetti Western film written and directed by Giuseppe Rosati and starring Gianni Garko and Stephen Boyd.

As such it features such latter-day genre elements as self-parody, guffaw humour, near-slapstick fight scenes (with accompanying sound effects), machine guns hidden in everyday household items, and bombastic villains.

Three American soldiers, Captain Chadwell, Lieutenant Junger and Sergeant Smith, are sent by Washington to recover the weaponry, or failing that to destroy them so they cannot be used against the army.

They get help from a blond adventurer, Koran, a bounty hunter who carries a pink umbrella and quotes extensively from the Moslem holy book (or so he claims it to be), whose primary interest is in capturing and turning in Angel Sanchez for the $1,000 price on his head.
