80s or maybe 90s film with team of guys wearing animal mask?

Hey everyone I was talking with my older brother and he cant seem to remember the name of a movie maybe someone here might know.

Ok he said the movie took place in a small town where he remembers a school house type place  in the woods and a black van. there was about 4 guys he said in which each had a different type of animal mask. He thinks there was a guy with a pig mask? But hes positive he remembers there being a skinny guy with a wolf mask and a black/red checker shirt on and was chasing a girl in the woods to a school house or maybe just a regular old house.

Id like to find this movie for him if anyone can help me find the name. Thanks!

Could it possibly be Fortress? (1986)

Here's an old thread I wrote back in 2007:

Hopefully I don't have my movies confused.
For some reason, I keep thinking the bad guys in Fortress wore animal masks.

Please correct me if I'm wrong.
