Duds and NK tactics:

The South Korean military is examining around twenty North Korean shells that failed to explode and were found lodged in concrete walls and in tree branches. Eighty of the 170 shells fired managed to land on the island. Roughly 90 rounds fell into the sea.
The number of duds is expected to increase, as troops are still combing the island for shells. South Korean authorities believe the duds and the shells that failed to reach the island were the result of North Korea’s aged equipment or flawed gunpowder and detonators.
Military officials believe North Korea achieved such extensive damage on the island despite the duds and the misses because it meticulously planned the attack. It used “time-on-target” (TOT) coordination, a military tactic in which all the munitions arrive at the same time at a designated target for maximum destruction.

A firing drill using the TOT method was carried out by North Korea in January near the Northern Limit Line, with around 100 rounds fired, which South Korean authorities think was a dress rehearsal for Tuesday’s attack.

They didn’t fire randomly but specifically targeted the military base on the island, including oil storage units, and 20,000 liters of oil were released, some catching on fire. They also targeted the post office, a supermarket and municipal buildings. Those structure were formerly military buildings, so the South Korean military suspects North Korea was planning from an old map.
