If they break through attacking the police & solders do you believe will stand take their weapons? No. They will be massacred.
Today the whole 4th Army corps in Evros has live ammunition exercises across the whole border. Has warned everyone to avoid the zones, especially the forest at Kastanies otherwise might get shot, or blown up by artillery shells falling next to the border inside the Greek territory.
Same to all the islands, as ASDEN announced all divisions on all islands are out for live ammunition training today and possibly tomorrow. So bullets flying due to exercises, better not come close to the islands. Someone angry might take aim....
If you're having to shoot live ammunition at unarmed people then something has gone very wrong. not saying that there are no circumstances under which you might - individual or small number of troops being surrounded/cut off by some angry mob etc..
But the shooting of a single migrant the other day - sounds highly unlikely it was really justified and more like someone lost control of a situation in which non-lethal solutions should have been used.
