In the past alot of the FBI HRT team members had a military SOF background. The FBI doesnt conduct overseas operations, not their mission. They have a pretty highspeed HRT Team and have alot of experienced former SOF Members and excellent training, in my opinion, within their mission guidelines they could be comparable. But they are a law enforcement agency versus Delta or USMC Force Recon, for example, I dont think they could match the insertion capabilities of their military counterparts. But once you start clearing a building its pretty much the same. Once again, this is just my opinion.
