===Armament===

The armament is the same as the [[BTR-60PB]] [[armoured personnel carrier]]; a [[14.5×114mm|14.5&nbsp;mm]] [[KPV heavy machine gun#KPVT|KPVT]] heavy machine gun with a coaxial [[7.62×54mmR|7.62&nbsp;mm]] [[PK machine gun#PKT|PKT]] general-purpose machine gun as a secondary weapon, both in a small conical BPU-1 turret mounted on the hull in a central position above the belly wheels.<ref name="Militarium.net" />

The 14.5&nbsp;mm KPVT heavy machine gun has a practical rate of fire of 150 rounds per minute and a cyclic rate of fire of 600 rounds per minute. It has an effective range during daylight operations of 2,000 m. It can penetrate 20&nbsp;mm of armour at a range of 1,000 m and 30&nbsp;mm of armour at a range of 500 m. It can also fire at air targets, in which case the tactical range is 1,400 m. It uses the 14.5&nbsp;mm API-T, 14.5&nbsp;mm I-T, 14.5&nbsp;mm HE-T, 14.5&nbsp;mm and MDZ type ammunition.

The 7.62&nbsp;mm PKT coaxial general-purpose machine gun has an effective range during day time operations of 1,000 m while the vehicle is stationary and from 400 m to 500 m while the vehicle is on the move. It is fired in 2 to 10 round bursts and has a practical rate of fire of 250 rounds per minute and a cyclic rate of fire of 650 rounds per minute. During daylight operations, the gunner uses the PP-61AM sight, which has a field of view of 23 degrees and x2.6 magnification.<ref name="Militarium.net" />

The BPU-1 turret is unusual because it has no top hatch opening. Contrary to the popular belief, the BPU-1 turret was originally designed for the BRDM-2. The turret was later used in the Soviet BTR-60PB, the Polish [[OT-64 SKOT#Poland|SKOT-2A]] and the Czechoslovak [[OT-64|OT-64A]]. The turret allows the armament to be elevated between −5 and +30 degrees. On the left side of the turret, there is an air inlet on the hull top. There are also two air-inlet louvers in the forward part of the engine compartment's roof and four smaller air-inlet louvers to the rear. Both sides have centrally placed vision blocks.

The vehicle armor, which is composed of welded steel, is sufficient against [[small arms]] fire and small shell fragments; but not enough for protection against big artillery fragments or .50-calibre machine gun fire, which can penetrate the BRDM-2's maximum armor of 14&nbsp;mm. The BRDM-2's tires are not protected by armour and are particularly vulnerable to puncture from fire of all kinds.<ref name="Militarium.net" /><ref name="Gary's Combat Vehicle Reference Guide" />

There are three different production lots, which have different cooling vents on the engine deck. The late production version has mushroom-type vents. It also has slightly modified turret and can elevate its armament to +60 degrees. Final production BRDM-2s have additional turret periscopes and a TNA-2 navigation apparatus.<ref name="Militarium.net" /><ref name="FAS" />
