Our 10 man team is getting new night vision, maybe pvs-14 but not sure, and we have never had GOOD training using our NV and shooting M4s or pistols. We have a few pvs-14s now but they are about 8 years old or older. They will helmet mounted and/or rifle mounted depending on the person. The 2 marksmen on the team run a 3.5x acog and rmr red dot so they are limited to helmet mounts only. The others have the choice. East coast and close to VA is preferred because my department is broke hahaha.
