Citat:So what are directed energy countermeasures? Rheinmetall AG and ADS GmbH are rather secretive about the principle and function of the countermeasures, but I have been able to piece together a likely countermeasure system.
The following photo shows the ADS-equipped Fuchs/Fox 1A8 after the ADS has defeated an RPG7 attack.

Circled in red, the rearmost sensor-countermeasure module is clearly altered from those of its cohort. The tube containing a slot located between each pair of sensor units has disappeared. (The lower cover is the correct height to be knocked off by the residual momentum of the RPG.)
The major clues about the operating principle of the ADS explosively-driven countermeasures include the following:
The AMAP-ADS has no moving parts;
The AMAP-ADS can be directed to attack a specific part of a threat projectile;
The AMAP-ADS countermeasures can cover a portion of adjacent sectors;
The AMAP-ADS produces no shrapnel or fragments.
Countermeasures consistent with these clues could be provided by a slightly curved linear shaped charge housed within each of the tubes connecting adjacent sensor housings. The actual form of the countermeasure would be a thin, flat fan of rapidly moving particulate material driven outward and downward by the explosion of the shaped charge.
The shaped charge mounting must hold the charge at a known position and angle, so that the plane of the flat fan is known. The fan must be wide enough to cover roughly half of the adjacent sectors as well as its own. Thus, when you know the trajectory of the threat and the position of the fan as a function of time, the countermeasure can intercept the threat by correctly timing the initiation of the shaped charge. The countermeasure can even be directed against a specific part of the threat projectile by making small adjustments to the initiation timing.
Finally, the fact that the countermeasures can kill a threat without production of shrapnel and debris begs the question - what material is the shaped charge liner made of ? The distance over which the flat fan must remain reasonably well focused is about 2 meters, which given the size of the countermeasure tubes is around 20 widths of the linear shaped charge.
There has to be a liner, as the distance of the shaped charge to the threat projectile is too great to use the Monroe effect itself - the high-speed detonation products would lose focus. But the liner can't produce shrapnel, so it can't be the usual copper or tungsten liner.
The likely solution is that the liner is made of a sintered or otherwise frangible metal. Such a liner will turn into a highly focused beam of sand, capable of the level of destruction required, but not representing a danger to anyone outside the immediate vicinity. No danger, that is, save for hearing loss. There is a reason that the official Israeli Defense Force designation for Trophy is Windbreaker!
State of the art of active close-in protection of armored vehicles has advanced with amazing speed in the past decade. Although Rheinmetall AG's AMAP-ADS may be top dog at the moment, improvements to Advanced Protection Systems are coming fast and furious. It will be fascinating to discover what such systems will look like in another decade!
Kontramere su najverovatnije kumulativne celije u kojima eksploziv pokrece nekakav materijal, koji se rasprskava u vazduhu, i time se unistava nadoilazeci projektil. Pomalo podseca na Ukrajinski Noz.

Danas oko 16:00 u blizini granicnog prelaza u Slavonskom Brodu sam vidio kolonu Patria u pratnji vojne policije izbrojao sam 13 komada otisle su u pravcu izlaza na auto put, vidi se da su potpuno nove i imale su sve neku vrstu borbene stanice ali sve je prekriveno ceradom tako da nemam ideje o cemu se tacno radi ali je djelovalo dosta visoko i glomazno. Nazalost nisam uspio upaliti na vrijeme kameru na mobitelu da slikam.

Kuvajćani u Spaladium Arenu dolaze po 120 hrvatskih oklopnjaka
http://m.slobodnadalmacija.hr/Dalmacija/Najnovije/.....fault.aspx
Ovaj će vojni sajam, kako se očekuje, proći u znaku delegacija s Bliskog istoka. Riječ je o vojnim predstavnicima najbogatijih arapskih zemalja poput Omana, Katara, Kuvajta, Saudijske Arabije, Bahreina, ali i Izraela te Libije.
Zanimljivo je da je “Đuro Đaković” ušao u uži krug izbora u Kuvajtu čija vojska treba 120 oklopnih vozila, pa su realne šanse da naš proizvođač tenkova i oklopnjaka iz Slavonskoga Broda taj vrijedni posao dobije. “Đakovićev” adut oklopnjak Patria AMV teško da će biti neprimjetan u dvorani u Lori.
