    The issue with this system and the Israeli Trophy or Chinese GL-5 is that any personnel that happens to be in the vicinity of the blast would be killed. The best way would be to develop a high-powered laser than can destroy such warheads at a greater distance. Or maybe even a "mini" CIWS-type system that uses small-arms-caliber ammunition.

    I wonder if the Russian Afghanit system has improved on this.

    No and Yes

    First The US Army is investing in three Hard kill APS system. Rafael Trophy though Leonardo which is going on Abrams. IMI ( being merged into Elbit ) Iron Fist and The American Artis Iron Curtain.
    Now at there most basic these are operating on the same principle. you fire a interceptor at a inbound projectile. But the Three systems work very differently.

    Trophy aka ASPRO-A or Windbreaker is the Only Proven APS system this side of the former iron Curtain ( the political one). Trophy uses Millimeter Wave radar to detect and range a inbound threat. The computer calculates trajectory speed and likely nature of the threat then adjusts one two Interceptor launchers and at a set time fires. The interceptor is a pack of 35 Explosively formed projectiles that operate on a shotgun principle to destroy the threat.
    The problem... Trophy has issues especially on light vehicles why? Explosively formed projectiles. If you look at a Trophy launcher behind the launcher there is a "box".
    Merkeva 4 Tank with Trophy HV note the octagonal radar and counter measure with launcher.

    That box is a shield to prevent damage to the host by the Explosive. this places limits on how many and where the launchers can be placed and the full size countermeasure system being added to Abrams and currently on Merkeva 4 cannot be mounted on a thin skinned vehicles as the explosive force would damage the host. This also limits the effects of the countermeasure. The countermeasure can rotate around but cannot defend from attack behind that shield. that Shield mind you is to protect sensitive things like optics, Machine guns or Tank commanders that have a sensitivity to Explosively formed projectiles. Near by Infantry also have a sensitivity to such systems... very bad for moral.
    Rafael introduced the MV version of the Trophy system for use on Medium weigh armored vehicles like IFV's, and these systems can be coupled with a Soft kill system. v Trophy MV being tested on a Stryker a number of years back.

    To get around this Rafael introduced a second APS system dubbed Trophy Light Vehicle which I will touch on later, but is not being looked at by the US Army.

    Iron Curtain Basically radars on the Vehicle detect a inbound threat, and calculate time of impact. before impact a Shaped charge set in a overhanging structure will fire. the Blast destroying the Threat, In theory, however leave the potential for top attack and offer no defense for Explosively formed projectiles, Sabots or ATGMS. Where they shine though is more against Recoiless weapons and offered best on Utility vehicles like Humvees, L-ATVs, MRAPS and the like. Interestingly the Army has been testing Iron Curtain on a Stryker. Iron Curtain works in a similar way to Trophy LV. These are a Different system from the Trophy HV and MV versions described above.
    This is a M-ATV mrap fitted with Iron Curtain

    This is a MATV with Trophy LV note optics an radar modules.

    as I said they Work in a similar manor but are not interchangeable although the Iron Curtain system does share it's radar with Iron Fist.

    Iron Fist by IMI ( now part of Elbit systems) works on a Third concept the US army has been testing it on a Bradley.
    This system works again having a radar to detect an inbound threat it then launches a Blast Grenade from one of up to 4 turret style launchers this grenade gets in about a foot or 2 of the threat and detonates.

    Iron fist has the nice feature that it can be mounted on just about any weight of vehicle and across the range of treats but with a critical limit to the number of countermeasures and risk to anything that might be on the top of the tank like say a Optical sighting system, remote weapon or a Tank Commander ( getting a large Blast fragmentation grenade fired at you is a pretty emotional event). to get around this IMI also introduced the Bright arrow system which combines a Iron fist launcher with a remote weapons station.

    The problem with a laser is power, The Problem with small arms ammo is although you might be able to take a RPG round Hardkill APS are intended to cover a range of threats including but not limited to RPGs, ATGM, HEAT shells, HESH shells, even some Sabot rounds can be countered depending on system. those demand a more substantial system to counter them.
    not likely. Afghanit is a evolution of Arena which is a evolution of Drozd which works in a way akin to GL5. these use fixed countermeasure launchers which place limits on there defenses The countermeasure is either a Explosively formed Projectile or Fragmentation warhead which means that any infantry in the path is going to have a very bad day.

    speaking of lasers, here's a hilarious quote from
    USAF prepares for rapid demo of high-energy laser weapon
    15 May, 2018 https://www.flightglobal.com/news/a...or-rapid-demo-of-high-energy-laser-we-448608/
    :


    Nearly a decade ago, the Air Force Research Laboratory wrapped testing of a 100kW-class chemical oxygen iodine laser on a Lockheed Martin C-130 after an Air Force Scientific Advisory Board report determined the weapon had “no tactical utility”.

    Funny.
    Those lasers though filled the aircraft's fuselage from nose to tail.
