This is 3 new heavily armored units that I made for humans faction: Tank-drone, Artillery MLRS system and Anti-aircraft defensive system. They are all based on amphibious undercarriage but have very different characteristics and combat assignments.

Tank Drone

Tank Drone is an unmanned, heavily armored fighting vehicle with tracks and a rail cannon that is designed for front-line combat. Tanks are mobile land weapon platforms, mounting a large-calibre cannon in a rotating gun turret. They combine this with heavy vehicle armor, and operational mobility. This unit is effective against large armored targets but not effective against infantry, due to the low rate of its cannon.

Artillery MLRS System

This is an armored, self-propelled, multiple rocket launcher. This type of rocket artillery is designed to destroy enemy buildings at a very long distance. Artillery System cannot find and choose targets themselves, so the commander must set the attack coordinates directly in the artillery mode. It cannot attack the enemy in close combat, so it is recommended to use them together with a group of tanks or infantry.

Drone Defender (anti-air and anti-infantry system)

Drone Defender is a powerful unmanned, anti-air and anti-infantry vehicle with x4 rapid-firing guns. Defenders are mobile land weapon platforms, mounting a high precision weapons in a rotating gun turret. They combine this with heavy vehicle armor, and operational mobility. This unit is effective against air units and enemy’s light infantry.

All these units can be created aboard the ARK.
