Korean Haubice K9: How many troops did they take?

[Just a week ago](https://defence24.pl/industry/end-of-supply-Korean-haubic) were delivered to the country the last ordered under the first executive contract of cannon-haubice K9A1 from Hanwha Aerospace. This meant that all specified vehicles had already reached the country, due to the fact that [the ones from the second contract](https://defence24.pl/power-arms/another-k9-do-do-polski-2) had arrived in mid-November in the number of 6 units. However, landing on Polish dirt is not the end of the process associated with this artillery, which must undergo the essential equipment before it reaches the military.
