The Swedish Navy originally planned to fit AMOS to the CB90 assault craft, but found that it was too small to carry it.

Sweden cancelled its acquisition of the AMOS in 2009 due to budget regulations by recommendations from Genomförandegruppen.

The next rounds are shot later with a slightly smaller angle and less propellant so that they fly a lower arc to the same target.

In a typical installation, mounted on a Patria AMV or a similar vehicle, the vehicle can dash to the next position roughly 30 seconds after initiating the 14-round salvo, leaving minimal time for detection and counter-attack by enemy; evasion is the primary means of self-protection.

Ammunition for AMOS includes the Strix guided round and a modification of the Spanish Instalaza MAT-120 120 mm Mortar Cargo Round (although the latter is restricted from the Finnish inventory because of Finnish partnership in the Ottawa Treaty abolishing landmines).
