The Kree Armor is a technologically advanced battlesuit that was used by the Accusers.
The battlesuit's strength allowed Ronan the Accuser to easily take down Drax the Destroyer and even send him flying several feet through a metal wall with a single hit. In his uniform, Ronan remained unphased by Drax's strongest hits.
During his fight with the Guardians of the Galaxy aboard the Dark Aster, Ronan took a direct blast from the Hadron Enforcer, a weapon that boasted the capacity to destroy a moon, without much harm. However, later armor was destroyed by the Guardians when they used the Power Stone to destroy Ronan.
