What is that on the M4

[Don H]

What is that square thing (near the front sight) attached to the M4? Also, while I'm asking dumb questions what is that attachment the soldiers have on their helmets?

I'll attach a photo.

Thanks!

Thats what you'd call a AN/PEQ-15, its a laser aiming device that uses both the visible and non-visible (infrared) lasers.

The infrared laser only being visible while wearing a set of Night Optical Devices (AKA, night vision)

The attachment on the front of the helmet is what you'd call a "rhino mount"; I can't remember the technical name, but its meant for attaching a swing arm which is then attached to the above mentioned Night Optical Devices (AKA, "NODs") so that you can always have a set of NOD's attached to your brain bucket.

And take it from me, having an awkward, heavy set of NODs hanging off the front of your K-pot is an uncomfortable and aggravating experience.

Thanks guys! I've seen them in photos and always wondered what they were. Thanks again!

Very close. The thing on the helmet is a nods plate. The rhino mount is what attaches to the plate and then the j-arm attaches to the rhino mount. Then the nods go on the j-arm.
100% correct about them being awkward though. Amazing what a rubber band around the j-arm and nods body can do to fix the alignment issues, though.
