Nice to see that it can actually help when applied intelligently

For the first couple of drones which detonate on impact. And not even those if you happen to encounter an FPV drone with a skilled operator who can just fly around that umbrella. However, traditionally tanks should be backed up by infantry and they can carry shotguns or whatever is the current best tool against drones, and in that case that Dragon Shield might actually be useful. But for a lone tank on recon mission or something similar it doesn't do much.
