AN GVS 5A
is the laser that we were using, however we now use the ESL, and I can't remember its designation of the top of my head(but looks very similar). However, it has a angle measuring head that give you the bearing to the tgt as well as the distance, and you can plug a GPS into it and get a grid to the tgt. Not extremely accurate bearings, but better than nothing. Our troops on Athena were using vector binos when they were light, if I remember correctly.
For light OPs the drills have not changed extensively, the only difference is some new lasers and possibily new radios. Mounted OPs do not even resemble those of 5 years ago, but that's about the vehicle.
