Basically means in war, if one side is attacking and one side is defending, the odds are in the defenders favor. As they can deploy mines, IEDs, traps, advance structural defenses, turrets, and ambushes locations.
Which is why it was so stupid to invade Ukraine in the first place and why it is going to be hard for Ukraine to take back territory.
