Jelaskan Awak dari BTR-60

In the BTR-60, the crew compartment is located in the front of the vehicle and had a roof - unlike the troop compartment, which first received one with the introduction of the BTR-60PA. In the BTR-60P and BTR-60PA, the crew consists of a driver and a commander. The driver's seat is on the left and commander's seat is on the right. In the BTR-60PAI, BTR-60PB and BTR-60PZ, the crew consists of a driver, a commander and a gunner. The position of the driver and commander stations remained unchanged in later models. The gunner operates the BPU-1 turret, using the PP-61A optical sight. In the BTR-60P, both the driver and commander manned their positions by entering the vehicle through the sides. The BTR-60PA introduced two hatches over their stations and crew members had to climb on top of the vehicle to use them. The entry method did not change in later production models. The BTR-60B introduced a side door for the gunner on the right side, and firing ports for both the driver and commander, and two for the gunner, one on each side. (For more information on the BTR-60's firing port see the troop compartment section). Both the driver and the commander have forward views through bulletproof windshields, onto which steel covers can be lowered. In the BTR-60P and BTR-60PA, the covers had vision slots, and additional slots on both sides of the crew compartment. These were removed in the BTR-60PB in favor of two periscopes on each side. In early models of the BTR-60P and BTR-60PA, only the driver had a periscope, while the commander had a removable OU-3 infrared searchlight. In the BTR-60PB, both the driver and the commander have three periscopes in the front (the commander's center periscope can be hard to see as it's just below the OU-3 infrared light). The vehicle was usually equipped with an R-113 radio; however,some models used the R-123. The initial BTR-60P production model lacked night-vision and had only four headlights (two infrared, two white, one of each kind per side, these remained in all BTR-60 models). Late BTR-60P models were fitted with night-vision; the TKN-1 connected with the OU-3 infrared searchlight for the commander and the TWN-2 for the driver. This remained unchanged in later models.
