North Korea Says Recent Missile Launch was a Short Notice Training Operation
North Korea claims that their recent launch of two missiles from railway cars was a short notice training operation to test readiness of the unit:

North Korea said Saturday its railway-based missile regiment conducted a firing drill a day earlier, with two tactical guided missiles hitting a set target in the East Sea.
The North’s official Korean Central News Agency (KCNA) reported the unit in North Pyongan Province bordering China staged the drill aimed at “checking and judging the proficiency” in its action procedures.
It marks the North’s second known missile test using a railway launch platform since the last one in September, and the country’s third show of force this year.
“The regiment received a firepower mission at short notice from the General Staff in the morning on Friday before swiftly moving to the firing ground, and precisely struck the set target in the East Sea of Korea with two tactical guided missiles,” the KCNA said.

YAWN…
It’s like reporting on how it’s raining outside, desperately trying to keep the tensions high.
As if the US and South Korea don’t do any test launches themselves.
