But, again, if it's forced to repack and go behind the smoke it still isnt doing anything useful, and now it's in a worse position when the smoke dissipates.
The goal isnt necessarily to force the MG back to base/kill it. If you can achieve your goals while the MG isnt doing anything useful then that is a win. While the MG is smoked you are able to set your troops in advantageous positions, and to capture territory that it might otherwise have been protecting.
Even just in a straight fight, smoking the enemy MG immediately takes it out of the equation, letting you defeat his remaining forces. If the MG hangs around after that, you've got it outnumbered and outmanoeuvred.
After dropping the smoke your Mortar is able to immediately start contributing damage to the remainder of the fight, so you're up an unit over your opponent regardless.
MG isnt doing anything useful but it will not acheive my goal that is recapture territory not just make enemy MG move to other point.
Many time when I use smoke(at rank > 200) My opposite just push their assgren in the smoke and wait for smoke end(or sometime hold the point too) with MG set behind. finally it is me who got forced to retreat.
Mortar smoking is not effective like use smoke form infantry while franking.
Finally It will lead to if I want to Counter 1 Mg, I need 1x mortar with atleast 1x infantry and for more effective I need 45 ammunition for grenade therefore this 60% of this trick will not work since enemy can just go capture another or flanking you back.
That why I said It not effective like other hard counter.
such as blobbing vs rocket truck , tank vs antitank. or light vehicle vs infantry which didn't have snare.
