The top of the rod looks like cylinder with a length of 50 mm and wchich cross section has a diameter of 13,8 mm. This way of defeating Explosive Reactive Armor uses the fact that Reactive Armor usually does not explode when hit by 20-30 mm rounds even if they perforate the cassette. The job of such a rod top design is to simulate a small caliber round and gradually increase the penetration channel without making the explosive elements inside the ERA explode

In case of HEAT warheads (used mostly in RPGs and ATGMs) the main way of defeating ERA is using a precursor. Precursors are divided into initiating and non-initiating ones. The first ones are supposed to make the ERA explode before the cumulative jet from the main charge reaches the armor. The main disadvantage of this solution is a need to create a relatively large time interval between the explosion of the precursor and the main HEAT charge. It must be done in order to give time for ERA to blow up after being initiated by the precursor. In reality majority of modern ERA (Relikt, ERAWA-2, BLAZER, ARAT) have multiple layers of reactive elements between metal plates and the time each layer explodes is delayed thus initiating precursors are nowadays most likely outdated.
More effective are the non-initiating precursors used in PzF-3IT600, RPG-29, RPG-28 and Kornet ATGMs. Their job is to punch a hole in ERA layers without initiating them allowing the main HEAT charge to pass through. Publications presented below show results of tests of penetrating two ERA layers covered by 14 mm armor plate by a precursor without initiating any of them. This precursor type allows the main HEAT charge to blow up right after without any time delays and the use of different layers and heavy moving armor plates in ERA can bring little effect against it
It sound very strange to me , are these part realistic ? I thought ERA doesn't explode when hit by small caliber bullet because these are not fast enough ? How can the tadem warhead and the long tip of APDS round penetrate ERA without make it explode?
