Experimental data on the punching of steel obstacles of 
thickness 200 mm are given, which show 
that, in collision and penetration, the particle and obstacle materials 
go out onto the rear side of the obstacle in the form of thin jets 
and their interaction with the package of electronic elements is responsible 
for the degradation of these elements located behind the obstacle.
