"Nice, pretty much your average CT Special Forces.Greek Police Special Anti Terrorist unit EKAM
Last picture, whats that on the top AWP, all weather optical aid? And the bottom one, M4 modified for sharpshooter role?"
Is a Night Vision Clip on Afocal, but don't know who made it. The Greek producer "Theon sensors" have a different looking one, maybe is a older model?
See here Theon model
The NX-135C is a Night Vision Clip-on Afocal Sight for mounting on top of optical day sights and laser range finders to provide night vision capability. The NX-135C features the biggest objective lens among the fielded night vision attachments (150 mm EFL, f# 1.7) and as such it offers increased recognition and identification ranges when attached to sniper rifle sights and laser range finders.
The NX-135C with its 6.85-degree FOV is closer to the narrow FOV of most large magnification sights and a perfect match to the field of view of most laser range finders. Hence, the NX-135C provides the most efficient utilisation of current high-performance image intensifiers.
The NX-135C also offers the largest output optics; 40mm to closely match the input apertures of the day optics onto which is attached.
Due to its exact, factory set, 1X magnification, the NX-135C mounts with special mounting brackets on LRFs and day sights without affecting their boresighting settings.
The user continues to operate the day sights as he would have done during the day, without the slightest change. Reticle readings, eye relief distances and shooting/observation practices remain the same as in day time.
For increased shooting accuracy, with the large magnification sights, the NX-135C is offered in a FAB (Field Adjustable Boresight) version equipped with elevation and azimuth (EL/AZ) controls as well as with Variable Gain Control capability.
The large aperture dichroic filter at the exit of the NX-135C allows the use of the LRFs or day optics during the day without prior removal of the NX-135C.
The NX-135C employs an inverting 18 mm, Generation 3, XD-4 or XR5 image intensifier assembly. Power is provided by one (1) AA size battery of any voltage between 1 and 5 volts. A variety of mounting brackets is available for different LRFs and optical sights.
