Videotapes of brutal hazing rituals and racist profanity among members of a celebrated Canadian military regiment have plunged the government of Prime Minister Jean Chretien into an embarrassing scandal involving some of its best-known international peacekeepers.

Portions of an amateur videotape aired on Canadian television this week showed drunken members of the Canadian Airborne Regiment in a 1992 hazing ritual in which recruits were forced to urinate, defecate and vomit, sometimes on one another. In scenes not broadcast, the elite paratroops reportedly are forced to ingest the excrement.

In another segment, a lone black recruit is led around on all fours at the end of a leash. On his bare back are scrawled the words: "I {heart} KKK."

The racist tenor of the videotape, shot at a military base in Ontario, was echoed in a second videotape also broadcast in part here this week.

As the camera captures daily life in the Canadian compound in Somalia in March 1993, Canada's elite peacekeeping troops refer repeatedly to "niggers" and "nignogs." The cameraman asks one member of the regiment how things are going in Somalia. Not so well, he replies: "We ain't killed enough niggers yet."

Defense Minister David Collenette said Wednesday that he was "outraged and disgusted" by the tapes. He ordered the country's top military officer, Gen. John de Chastelain, who was ambassador to the White House in 1993, to report to him Monday with a recommendation for action.

Prime Minister Jean Chretien, on an official visit to Trinidad, left no doubt of his feelings on the future of the deeply troubled airborne regiment: "If we have to dismantle it, we'll dismantle it. I have no problem with that at all."

The scenes of a military regiment violently out of control confirmed a perception already being etched in the public mind here.

Nine soldiers from the regiment in Canada's peacekeeping mission in Somalia were court-martialed last year in the torture and beating death of a Somali teenager suspected of thievery. The crime was captured in still photographs shot as "mementos" by the perpetrators. The pictures were published here last fall.

The Somali proceeding brought to light a violent and racist culture in the 660-member airborne regiment, whose members wear maroon berets and paratrooper insignia. Some regiment members in Somalia were revealed to belong to white supremacist organizations and were captured on film wearing Confederate paraphernalia.

"There's a certain mentality that comes from jumping out of airplanes," said Desmond Morton, one of Canada's leading military historians. The "international paratrooper ethos" of fearless Rambos, he said, has made airborne regiments "a nuisance in every country that's had them."

Editorials, commentators on the military and callers to radio talk shows across Canada buzzed with appalled reaction to the videotapes today.

"Where were the sergeants? Where were the officers?" Morton asked. Retired colonel Shirley Robinson declared on television: "Their officers have been condoning this behavior and perhaps even encouraging it."

Few voices were raised in defense of maintaining the regiment and none in defense of the conduct on display, which reminded Toronto Sun columnist Lorrie Goldstein of "a real-life 'Apocalypse Now.' "

Calling for the Airborne to be disbanded, The Toronto Star's lead editorial today concluded: "These activities by paratroopers who are walking time bombs reveal dark and persistent problems. They tarnish Canada's image abroad, the Canadian military, our peacekeepers in the field, and decent, disciplined members of the Airborne itself." Jim Allen, another retired colonel and ex-regiment member, said on a national talk show: "It's time to start over again, because you're never going to beat that rap."

The volume of public revulsion at the spectacle on the tapes, analysts speculated, was likely to force a decision about the regiment's status well in advance of a public inquiry that had been scheduled to examine charges of brutality against Somali prisoners.

Another possible casualty of the scandal, analysts said, may be the Chretien government's tentative plans to send a unit of the Canadian Airborne Regiment as peacekeepers in Croatia in April.
