See query. ([Wiki Trophy](https://en.m.wikipedia.org/wiki/Trophy_(countermeasure)), [Wiki Iron Fist](https://en.m.wikipedia.org/wiki/Iron_Fist_(countermeasure))). The former’s by Rafael and IAI, the latter by IMI.

[The US Army just announced a purchase of Trophy](https://en.m.wikipedia.org/wiki/Trophy_(countermeasure)#Tests_by_the_United_States), and in Israel they’re talking about a “combination” of the two weapon systems—hence query.

Important addition to OP: throw Raytheon ["Quick Kill”](https://en.m.wikipedia.org/wiki/Trophy_(countermeasure)#Tests_by_the_United_States) into the mix…

The main difference I’m familiar with is that Trophy’s countermeasure is basically a shotgun blast aimed in the general vicinity of the incoming munition, whereas Iron Fist is an anti-missile missile (with small blast warhead and zero-fragmentation casing). The latter makes Iron Fist hypothetically safer for accompanying infantry.

ETA: Quick Kill is a US development that appears functionally equivalent to Iron Fist.

The Trophy is basically an Israeli version of the [USSR’s Drozd from the late 70’s.](https://en.wikipedia.org/wiki/Drozd). The Red Army abandoned it as impractial, although their Naval Infantry (their version of Marines) used them. It uses a RADAR. and has a limited field of view (about 60-90 deg), nesseciting multiple systems on the same tank. While Iron Fist is like the Russian [Arena](https://en.wikipedia.org/wiki/Arena_(countermeasure)) a higher protection zone and also used passive sensors instead of active ones (RADAR is susceptible to counter measures).
