I've heard this comparison so many times I ran some experiments. A number 8 1.5" coated decking screw inserted into two one by pine boards through the grain by a hammer holds about half as well as one inserted using a screwdriver. One hit to drive the screw is better than several, but a two hit approach (one to set the angle of the screw tip, the second to send it home) was most reliable. Drilling a pilot hole before hammering improves things pretty significantly, up towards 3/4 of the holding power of a driver driven screw.
On the other hand, even very slight misalignment between the hammer swing and the screw can result in failure, and the board was always more damaged by a hammer inserted screw.
I’m amazed and delighted that Ukrainian troops have managed to occupy a part of Russia for so long. I thought they would be driven out in a day or two. This is pathetic (and hilarious). It reminds me of the early days of the war, when Russia thought they would take Kyiv in less than a week.
It just drives the point more that the Russian military is nowhere near the level the rest of the world thought it was.
Russia should have easily had air superiority within a day and been able to run through to Kyiv in a week. Especially with the build up on the border leading up to the invasion.
It also brings into question their overall nuclear capability. Like whether they're capable of MAD-level deterrence anymore. Even though it only takes a few nukes to destroy everything anyway, their massive stockpiles have likely deteriorated irreparably over the last 30-40 years and they've been lying to themselves in reports so no one had to take any blame.
If I was a corrupt Russian general, embezzling funds meant for nuclear deterrence upkeep would be a pretty safe bet since they are the weapons least likely to ever be used and thus least likely to be found out.
