U.S. Army getting its first light tanks in more than 50 years.

Yes, they can; all it takes is a rise or a hill to park it on. In any case, artillery/tank combos are all the rage now.

Artanks are possible because "surveying" is no longer required for indirect fires. At one time, an artillery battery required some time to determine it's exact position and carefully "lay" their guns into a solid, level position. However, modern self-propelled artillery can use GPS to determine its exact position instantly, and computer software can automatically adjust for a unleveled gun. Artanks do not require the development of new technology, only the merger of direct and indirect fire controls systems into a modified turret.

 

And I will say it yet again, and am done as you do not seem to get it.

These are not tanks, these will not be used as tanks, these are infantry support vehicles.

You fail to grasp any of this, and seem obsessed with trying to force them into being something they are not.

 

And that's what makes them rolling coffins.
