The UEF T3 Support Armored Command Unit is a UEF command unit, providing direct fire and building support/resource generation. Deployed at the Quantum gateway, the UEF uses it as support to the Main Command Unit or ACU.
The UEF Support-ACU shines as a combat support unit; its Shield Generator Field has 52,000 HP making it by far the toughest shield in the game (and giving the S-ACU 84,000 total HP). It can also inflict decent damage when upgraded with the Energy Accelerator, which doubles the DPS due to increased rate of fire, and Heavy Plasma Refractor for area of effect. This strong combination is known as the "Rambo" style, but is not invincible. In battle it functions best as an escort for Percivals.

Tips[]

Two Basic UEF Support Command Units
Note that even when upgraded with the Shield Generator Field the game recognizes the sACU as an engineer unit rather than a shield unit and assigns it to the back of any formations, rather than putting it in a position where its shield can cover your units. Ergo, if you want to use the sACU in formations you will require considerable amounts of micro. A possible workaround is attaching it by the assist command, and using the formation move to fix it in relative position.
The Enhanced Sensor System is a useful alternative for getting intelligence, especially against opponents employing stealth. A notable use is against Cybran T3 Air or SCUs, and so defensive sensors are useful if the SCU is not actively in combat (where the LCH accelerator would be preferred).
The ultimate power of the UEF SCU is its ability to, when upgraded with a bubble shield, march straight onto a battlefield and safely build structures such as point defence guns by constructing them under the security of its shield, or reclaiming significant amounts of mass from experimental wrecks. While the SCU itself has little firepower, the ability to build T3 Ravager point defences directly within firing range of the enemy is a fearsome weapon indeed.
