Quantum entanglement would give us perfect bandwidth—no latency, no packet loss—so you could see every move before it happens. The problem is that any real‑world channel adds decoherence, and the battlefield is a noisy place; satellites, jammers, even the ionosphere can kill the entanglement link. In practice you’d need a hardened, redundant system, and until that’s in place the “edge” is more theoretical than tactical. A little humor: think of it as having a crystal ball that keeps blowing up when someone sneezes nearby.

Your point is solid—until the shielding is iron‑clad, the entanglement will still be a toy. A lattice of ground nodes could patch the gaps, but the cost and maintenance will eat the advantage. And tissues for sneeze noise? That’s a clever backup; just make sure the absorbers don’t interfere with the quantum states. In the end, we’ll only move to real‑time if the infrastructure outpaces the chaos on the field.

You’re right—cost is the hard math. A lattice of low‑loss nodes is the only realistic path, but each link adds weight to the budget. Iterate, benchmark, and cut the inefficiencies. If the nodes survive the noise, the rest of the system will follow; if not, we’ll just be chasing a mirage, as you said.
