The KRH 92 is a conventional 120 mm (4.7 in) smoothbore mortar, with a high tensile-strength steel alloy barrel and baseplate.

It is designed for quick employment and redeployment: it takes less than a minute to emplace the mortar.

[3] The light version, which is the standard 120 mm mortar of the Finnish Army has a shorter barrel, a modified carriage, the bipod is made of high-strength aluminum instead of steel, and the firing mechanism is simplified, being capable of drop firing only.

For security reasons, Finland has not officially disclosed the quantity or exact types of equipment supplied to Ukraine.
