is this the almost same ability where bomb drop like hell when using Encirclement??
How does the ability work tho?..
You cast it on an area, a circle appears on the map, and any enemy vehicles will get intermittently struck with shells that stun or apply criticals (e.g. engine damage). Any infantry / weapon teams will periodically get a small light mortar barrage that does a bit of damage and suppression. To stop this from happening either line of sight must be obscured, or units must leave the area of effect.
It's not so dangerous in and of itself, its more that when combined with a well timed armor push, it can result in the total destruction of whole forces of tanks.
