'U.S. Navy animated training film by Hugh Harman Productions. Features the character Private McGillicuddy. Used to train U.S. Marines about dysentery & safe latrine practices.'

Originally a public domain film, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.

The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

A latrine is a toilet or an even simpler facility which is used as a toilet within a sanitation system. For example, it can be a communal trench in the earth in a camp to be used as emergency sanitation, a hole in the ground (pit latrine), or more advanced designs, including pour-flush systems.

The term "latrine" is still commonly used in emergency sanitation situations. Nowadays, the word "toilet" is more commonly used than "latrine", except for simple systems like "pit latrine" or "trench latrine".

The use of latrines was a major advancement in sanitation over more basic practices such as open defecation, and helped control the spread of many waterborne diseases...

The head (pl. heads) is a ship's toilet. The name derives from sailing ships in which the toilet area for the regular sailors was placed at the head or bow of the ship...

In sailing ships, the toilet was placed in the bow somewhat above the water line with vents or slots cut near the floor level allowing normal wave action to wash out the facility. Only the captain had a private toilet near his quarters, at the stern of the ship in the quarter gallery.

In many modern boats, the heads look similar to seated flush toilets but use a system of valves and pumps that brings sea water into the toilet and pumps the waste out through the hull (in place of the more normal cistern and plumbing trap) to a drain. In small boats the pump is often hand operated. The pump on a marine toilet operates in a "wet" mode and a "dry" mode. The cleaning mechanism is easily blocked if too much toilet paper or other fibrous material is put down the pan.

Submarine heads face the problem that at greater depths higher water pressure makes it harder to pump the waste out through the hull. As a result, early systems could be complicated, with the head fitted to the US Navy S class submarine being described as almost taking an engineer to operate. Making a mistake resulted in waste or seawater being forcibly expelled back into the hull of the submarine. This caused the loss of German submarine U-1206...
