model Mark II version of the Israeli Merkava, the British Challenger 2 and the Russian T-90. In August 2006, in al-Amarah, in Iraq, a Soviet RPG-29 damaged the front underside of a Challenger 2 tank, detonating ERA in the area of the driver's cabin. The driver lost part of a foot and two more of the crew were injured, but the driver was able to reverse to an aid post. The incident was not made public until May 2007; in response to accusations, the MoD said "We have never claimed that the Challenger 2 is impenetrable." Since then, the ERA has been replaced with a Dorchester block and the steel underbelly lined with armor, as part of the 'Streetfighter' upgrade, which was a direct response to this incident. In May 2008, The New York Times disclosed that an American M1 tank had also been damaged by an RPG-29 in Iraq. The American army is ranking the RPG-29 threat to American armor as high; they have refused to allow the newly formed Iraqi army to buy it, fearing that it would fall into the hands of insurgents. Various armies and manufacturers have developed add-on tank armor and other systems for urban combat, such as the Tank Urban Survival Kit (TUSK) for M1 Abrams, slat armor for the Stryker, ERA kit for the FV432, AZUR for Leclerc, and others. Similar solutions are active protection systems (APS), engaging and destroying closing projectiles, such as the Russian Drozd and Arena, as well as the recent Israeli TROPHY Active Protection System. The RPG-30 was designed to address the threat of active protection systems on tanks by using a false target to trick the APS. The RPG-30 shares a close resemblance with the RPG-27 in that it is a man-portable, disposable anti-tank rocket launcher with a single shot capacity. However, unlike the RPG-27, there is a smaller diameter precursor round in a smaller side barrel tube in addition to the main round in the main tube. This precursor round acts as a false target, tricking the target's active protection system into engaging it, allowing the main round a clear path into the target, while the APS is stuck in the 0.2–0.4 second delay it needs to start its next engagement. Recent German systems were able to reduce reaction delay to mere milliseconds, cancelling this advantage. The PG-30 is the main round of the RPG-30. The round
