Kiwi,
The goggles are used for protection from flying splinters if you use a ram and possible flying dust and particles if a NFD (flashbang) is deployed. When your past that point they are an impediment. Just strip them off the helmet once inside and FIDO ("screw" it, drive on). You can come back and get them later.
The best vision possible is one of the most important elements of working safely. If they won't stop a bullet why mess with them once inside ??? Why you don't employ gas when you don't have to, working in a mask is a REAL pain.
