Sorry RPG but now you are just ignoring what is being posted...
so it seems russians have finally recognised their 1.flawed doctrine and 2.that their weapons are aging :
Did you even read that page?
Top attack weapons have always been desirable, but not at the cost of being as pointless as Javelin.
Pointless in the sense of being far to expensive to actually use or be widely deployed except in armed forces used to pssing away taxpayers money.
so the result is=
1.the top attack version ,
2. and new 152mm calibre warhead at total system weight of 14,5kg ,and 2.500m range , hmm very good i say.
for comparison rpg--7 with 105mm tandem warhead has 11,5kg weight and 200m effective range.
Except it mentions two weapons... one being an ATGM that will likely coexist with the Metis-M1 simply because the latter is so cheap and simple and portable it is unlikely to be replaced quickly... it calls it a medium range ATGM, which I would suggest would fit quite nicely between the short range ATGM (Metis-M1) and the Kornet-EM long range system.
The short range system uses two different types of warhead with the top attack version using a gyro stabiliser and thrust vector control to whip the warhead 90 degrees, presumably using a sensitive magnetic anomaly detector to sense the presence of the tank.
The Russians have never had anything against the top attack flight profile, but the method of reliably achieving such an attack profile had to be cheap and simple but effective so that it can be widely deployed and use in numbers to make it effective.
Javelin is an example of how not to do it... a thermal sight in the launcher is one thing... fitting it to every missile however means they are very expensive.
The idea of making them able to be used in a dumb command to line of sight mode actually makes them worse because a much cheaper and simpler missile like Metis-M1 uses that mode of firing... as does Javelin when firing on targets with little or no IR signature.
Fitting a thermal imager to Metis-M1 gives it all the all weather, day/night launch capability and target detection capacity of Javelin, but at less than $20K per missile it is much cheaper to use in numbers against a range of targets like MG nests and sniper positions than Javelin.
Of course the troops in the field don't care how much it costs so they will use it against anything and everything... again its cost counts against it.
