Ecu

=
''"...Turn your shield to the attacking enemy to protect yourself from incoming fire. Shield has certain durability and can be destroyed. Doesn't work against weapons which deal splash damage (SURA-F Pinata, CRV Pin, SM NORICUM)..." ~ In-game description.''=====

The Écu is one of two shield weapons in the game (The other being the Ancile), and can be equipped to any slot located on an "arm". Large and sturdy, this barrier serves to absorb incoming attacks, so it takes the damage instead of the robot.

The Écu blocks damage by possessing it's own hit points. When a projectile hits the Écu, the shield takes the hit instead of the robot.

Players are then forced to rotate each time they want to put the shield up. Even then, this is no guarantee of blocking hits, because some rocket weapons, like the SURA-F Pinata, can deal splash AoE through the shield and still inflict damage on the robot.

The Ecu may only be mounted on 'arm' hardpoints, not on 'shoulder' hardpoints. The hardpoints the Ecu cannot be mounted onto are: The shield can be used to protect yourself while reloading.
 * The top hardpoint on the Gepard.
 * The only hardpoint on the Schütze.
 * Neither of the upper two hardpoints on the GL. Patton.
 * The heavy hardpoint on the Vityaz.
 * The heavy hardpoint on the Boa.
 * The light and heavy hardpoints on the Golem.
 * None of the Fury's hardpoints.
 * Neither the middle light hardpoint nor the heavy hardpoint on the Leo.
 * Neither of the light hardpoints on the Griffin.
 * Neither of the heavy hardpoints on the Natasha.
 * Neither of the medium hard points on the Rhino.

After too much damage, the shield will break off like a destroyed weapon, unusable.

Trivia

 * The Écu comes in either left-handed or right-handed variations. They must be bought separately and cannot be used interchangeably.

 * The Écu comes from Louis IX, in that he made coins with the same name, with a shield and the family emblem.
