It is mine favorite weapon in CM The best light mortars you can find in Romanian and Italian army - fast, and with 65 rounds x 65 mm that can stop all attack and knock down all guns.
Primary use of mortars for me is knocking down enemy guns
I use them separately from theirs platoons and usually I make mortars platoon
They first made panic on infantry riding on tanks and then during rest of the fight they destroyed several guns (3 probably) and killed a lot of infantry.
as you can see only Company HQ could be visible to enemy.
