A Russian RPG-28 Klyukva (Cranberry) handheld anti-tank grenade launcher was tested in the presence of journalists from the Russian news network Zvezda; the video shows the RPG-28's shell easily piercing through a reinforced concrete wall two meters thick.
"The shock wave was so powerful that we could hear the tremble of the bunker from where we watched the test. Also, a car alarm system was set off a few kilometers away due to the grenade launcher firing," journalists said.
The RPG-28, a portable, disposable anti-tank rocket launcher with a single shot capacity, closely resembles the RPG-27.
The 12-kg RPG-28 has a larger diameter round which allows it to achieve higher armor penetration performance. The grenade launcher's round is a 125-mm tandem shaped charge with a range of 300 meters.
