this name is singijeon=hwajun=fired off arrows(신기전, 화전).
The Joseon navy used rockets to burn Japanese ships.
"08-July (Extension) [August 14th, Gregorian calendar]
They rushed forward and fired off arrows and arrows, and they were like wind and thunder.
The enemy's ship was set on fire and shot at the enemy."
most of Joseon government troops is actually similar to the conscripts.
so Joseon uibyong(guerrilas) and Joseon government troops is little different.
The different is
Joseon uibyoung`s general = a local yangban(similar aristocrat, but aristocrat and yangban is different thing.)
Joseon government troops`s general = a general appointed by the government
And whether it was uibyoung or government troops, the government eventually controlled it.
This is because the administrative power of the Joseon government was enough to receive regional reports even during the war.
in my personal opinion
Joseon army in second Qing-Joseon war is good look.
but Joseon government in second Qing-Joseon war is didn't get a good look.
because commanders who experienced the Imjin War to control the war either died of old age or died during the first Qing-Joseon War.
