    The cage is supposed to detonate the heat round (which both the rpg and javelin have to some extent) prior to impacting the actual armor. There’s usually a shaped charge in the round and a stand off with the primer in it that ignites the round at the convergence point of the shaped charge. If you set that off prior to the round hitting the armor it’ll just splatter against the armor rather than penetrate it. Some weapons have a tandem charge, that has two shaped charges to help it get through ERA or I imagine cope cages.






  • As others have said, you can’t passively bypass GNSS jamming. The signal more or less has the same amount of power as a 60 watt light bulb, transmitted from a satellite out in Medium Earth Orbit. You throw enough energy at the same frequency as the signal and it’s over. There are ways to improve the receivers resilience by giving it more signals to connect to (GPS, Galileo, GLONASS, BeiDou) or several signals being transmitted by the same constellation (L1, L2, L5).

    Also, many different systems occupy pretty much the same frequencies, just with different characteristics which makes all the signals more susceptible.

    It starts out super concentrated and spreads out at a 35-45 degree angle from the end of the gun tube and becomes less concentrated the further out it gets. There’s a chance it wouldn’t hit somebody a hundred meters out but anybody left would get hit with the coaxial mounted machine gun.
