This is the intense moment homeless veteran and trolling man get into heated argument during Hollywood's Halloween (October 31).

A man drinking a beer approached a group of homeless people sleeping on Hollywood Boulevard at around 1:45 am.

The man trolled the group of sleeping people by taunting them, questioning why they'd want such difficult positions and accusing them of ruining the public space.

One of the sleeping arose to scream that he is US Army veteran and he served to protect his country, telling the troll to "shut up and get lost."

The veteran then got up, flung off his shirt and went after the troll, who backed away quickly.

Later, the veteran pulled out a hunting knife at the troll after the troll ​returned and threatened the group with his now-empty beer bottle.
