Russian social media has been circulating images of a Ukrainian drone bomb which is square with a metal point like the ground spike for a fence post.
This is a penetrating weapon, as a sticker on the bomb proclaims, and it has Russian military bloggers worried.
FPVs and drone bombing have driven Russian forces underground into bunkers and forced them to cover roads and facilities with nets, wire cages and steel mesh.
A few weeks ago Russian reports started circulating of a new drone bomb punching through such defenses.
The fence post bomb, primitive as it looks, follows the same pattern.
Since fence post anchors already exist, there was no need to reinvent them.
Comparison with other items in the image, notably the Tolsen 300 mm hacksaw, suggests that the design is based on spike for a standard 100mm fence post. »
