Yes if you could get the van up to speed.
If the van appeared and was high centered on some rocks, and the SWAT team
tenaciously had no idea what was going on such that they did not fight back as the raptors got thru the windows, the SWAT team would be in trouble.
But if the SWAT van appeared on I80 it could just drive. The van could outrun the raptors. I know the raptors would set off after it because they will not stop attacking. Once the van got a little distance it could turn around and come back at the raptors. This is a doughty van and hitting the raptors at 60 miles per hours will be ok for the van and sort most of the raptors out. If some were still interested in chasing the van, the van could repeat this maneuver.
I have to think that you would need seriously intoxicated SWAT team members to not get some rough idea of what was going on when a monster poked its bitey head thru the window and starting making biting motions. And biting sounds, and probably drool. It is a pretty weak SWAT team that does not have fighting equipment of some kind in the van. I expect they would use some of that stuff on the monster's heads.
