Imagine 1/3rd of the shells you fire at the enemy didn't do anything. This was woulda been over a long time ago

Given the way that Russian made weapons seem to work I’d agree that the dud rate is probably not what’s described. It’s probably closer to 5% US did rate and 60% for Russian made garbage. I mean, I remember the start of the war when they had videos all over of cluster munitions that were unexploded.

If there’s one thing the US values it’s value-per-dollar, and dud bombs not working would be bad business.

Also, to the OPs question about using them to make drone bombs. They would be crazy to do that. Especially when the battlefield as it’s described talks about trenches with mines on top making it difficult to run Bradley’s and Challengers over. My guess is they’ll use the cluster munitions to carpet an area, detonate any mines underground and clear out trenches, and then push forward through the newly opened line.
