"client state of Belarus" ... In the last 4 yrs, I actually see a bit more of independence of Belarus from Moscow than Germany, Lithuania or Finland does from Washington DC.... Belorussian at least takes weeks or months to comply with Moscow's demands... it is always overnight for Europeans!

Militarily speaking, I don't see this being much of a deterrent either. In such a vast terrain, it would not be hard for Russia to get hold of one and reverse engineer it to disable it (presumably they will be remote controlled and disabled). But even with that, just a large unmanned machine can go in front triggering the mines and breach the line overnight. Again, due to the vast amount of land border and civilian population, it will be a very thin line. Of course, that takes the assumption that Russia had any interest of invading any land beyond Ukraine, that I would rate it as zero (unless invaded first or an total embargo on Kaliningrad!). After NATO's progress fiasco showed in Ukraine, I think from now, the industry and certain politicians just view NATO as a cash cow for the remaining of its existence and less and less expenses share of the pie will be for innovation and readiness.
