For the first time in a live NATO operation, Spain is deploying a functioning 5G military network at its base in Lešť, Slovakia — where it leads the alliance's largest multinational battlegroup. The €3 million experiment asks a question that no army has yet answered in the field: whether next-generation connectivity can hold together the many simultaneous threads of modern warfare. If it succeeds, the lessons drawn from 800 soldiers and 200 vehicles on Europe's eastern flank may quietly rewrite how allied forces communicate for a generation.
