Canada's tanks

[Kirkhill]

Or make a UGV Ontos like system.

Years ago I saw a Mike Loade video where he postulated that the way the ancient chariotse were used was not in a head on charge but as a stream of chariots running across the enemy's front while the archers poured in arrows like machine guns. When they ran out of arrows or targets they galloped off the line and returned to the rear to rearm and reset for another run.

In the 16th century, with the invention of the wheel lock pistol the cavalry re-invented the tactic as the caracole.

Lots of caracoling UGVs?

To add to the above post:

The Rocket Sherman - T34 CalliopeThe Rocket Launcher T34 (Calliope) was a tank-mounted multiple rocket launcher used by the United States Army during World War II. The launcher was placed atop the M4 Sherman, with its prominent vertical side frames anchored to the turret's sides and fired a barrage of 4.5-inch (114 mm) M8 rockets from 60 launch tubes.
