According to the video’s source, this is Stick Commander footage of 3 PPCLI paratroopers being “off-dropped”. The paratrooper who found the forest amazingly scraped by with only a minor foot injury.

“PPCLI” is an acronym that stands for Princess Patricia’s Canadian Light Infantry. They’re often referred to as “The Patricias”. They’re one of three Regular Force infantry units of the Canadian Army.
