Yesterday, Sky News spoke with military analyst Professor Michael Clarke about the effectiveness of Russian drone and missile strikes on Ukraine.
He told presenter Gareth Barlow that the level of damage that can be inflicted cannot be underestimated, as evidenced by the loss of life across the country from such attacks.
He also pointed out that that even though Ukraine's air force often manages to divert drones away from its cities using electronic warfare, the explosive warheads on them will still detonate when they land somewhere else.
However, Clarke explains that overnight drone attacks on cities have a larger effect on morale than on tactical battlefield results.
"Is it making a strategic difference? Probably not," he says.
"The things that make a difference for the Russians are the glide bombs - things that can affect the front lines.
"The drones are certainly bringing misery to the civilian population because they're forcing them to spend nights in the air raid shelters and in the tube stations in Kyiv rather than at home. So it has a morale effect."
