On a more serious note, a single regiment of ATAGS can fire 108 rounds in 30 seconds and have them all land on target at the exact same time. Imagine what it would be like to stand in the line of fire of an Indian Arty regiment equipped with ATAGS. One moment its all quiet and you are sitting in your trench or patrolling on foot. The next instant, the world around you explodes as 108 arty shells of 155mm land on you and your buddies within a span of 2 seconds, levelling the area and effectively suppressing your unit. 2 minutes later, the ATAGS regiment has already scooted and an Indian Infantry formation is charging your lines. Half your unit is dead or wounded, another half have been shell shocked and lost their will to fight. That leaves you alone to repel the attack. Good luck.
There is no Western towed field howitzer that can do even half of such a fire mission.
Then there is the fact that Westerners rely mostly on the M777 which loads a 155X39 mm round, thereby limiting the range of the gun.
