Noticeable for launching shells at the enemy, the Mortar is a good support unit.
Due to their slow rate of fire, it is common for players to stick 2-3 in a Mortar Pit which allows for an average of 3-4 mortar shells fired every 5 seconds or so.
Your good old mortar is a perfect weapon to shred enemy infantry, especially in Mortar Pits. It is not really good in fight with tanks, but it acts like German soldiers' worst nightmare to match your Sherman tank and artillery.
The worst thing is the fact that he is a priority target. This means that it is commonly shot at, and may be pinned. Your mortars have another drawback: they can't fire in Bunkers or under Cam nets, and they need a direct Line of Sight to shoot if not paired with a Scout.
This mortar is probably the M2 Mortar, as they were used as a cheap alternative to fire support by the US during World War 2. It could sustain 18 rounds/minute (weirdly, our mortar has much slower fire rate). It also had a long range for a mortar of its caliber (60mm).
Mortars were extremely deadly while on the field. Being hit by one or even being near the blast radius would immediately result in a lost limb, severe shock, severe trauma, and of course, death. Hearing the sound of the blast after the shell had hit the ground was intimidating and mind nerving to say the least. The range and accuracy were completely random, and that was the scariest part about them, they could land anywhere. This weapon has serviced in WWII, Korean War, and the Vietnam War.
There have been reports of actual guerrilla fighters and terrorists using this weapon.
