a 360 deg FOV. The M17 lacks stabilization, with the observation of the environment around not being efficient. On the left side of each of the periscopes, one may find a button that can align the turret (gunner's sight) with the optical axis of the given periscope. This robust hunter-killer system represents the level of advancement equivalent to the technologies of the 1960s. It is inferior when compared to the BMP-2 that features the moving TKN-3B system that is independent of the turret. Both the commander and the gunner have two 10 inch displays at their disposal, to display imagery from the daytime camera or the thermal imaging one. The gunner has a single M17 periscope at his disposal, with a FOV of 36 degrees. Kollsman DNRS-288 stabilized day/ night sight is the primary instrument used by the gunner. The optical tract with the ocular plays a secondary role, in relation to the imagery that is electronically transmitted to the crew-member displays. DNRS-288 features a laser rangefinder, a digital CCD camera that offers imagery that stays in focus at a distance of up to 1,200 m and features a 752x582 pixel sensor, with 12x magnification and FOV ranging from 4 to 10 degrees when the day/visible light channel is used. The night track uses the Galileo Avionica TILDE FC thermal imaging camera with two FOVs (wide and narrow). The sight features a fixed set of reticle for any of the 30 mm rounds for the Mk 44 gun. The crosshair can also be used for the coupled GPMG. The range measured by the rangefinder is displayed in the Kollsman sight ocular and on the gunner and commander displays. The sight is coupled with the ballistic computer that receives the weather data (temperature, pressure, wind direction, and speed) and data from the turret sensors (elevation, turret rotation speed, vehicle movement direction and angle, and so on). The FCS also makes use of the data pertaining to the powder temperature. The adjustments are applied with regards to the crosshair, after a few seconds of tracking the target with a proper button being held by the gunner and with a known range to the target. This causes troubles similar to the ones evident in the case of the PT-91 MBT or case of the Austrian Ulan design. The crosshair moves to accommodate for the adjustment and it needs to be placed over the target again to shoot. This wastes precious seconds and increases the probability of error or erroneous firing solutions if the target changes its speed or direction of movement. Rosomak crews have a primitive auto tracker system at their disposal. Once the target is in the crosshair the turret www.fragoutmag.com
