　 　　Sub-weapon “Barrier Bit Deployment [Defense]” 　　　・Launches barrier bits linked to the Mega Beam Shield. 　　　　After the weapon is used, barrier bits are deployed, 　　　　with melee and ranged attacks negated by an inverted triangular I-field. 　　　　Tackling power is also enhanced while deployed. 　　　・Reloading, taking a melee attack to the MS, 　　　　or performing a counter while Barrier Bits are deployed will release the deployment. 　　　　If your unit pulls off a counter disabling the barrier bits, the Heat Gauge will fully recover.

　 　　Sub-weapon “Barrier Bit Deployment [Wide Defense]” 　　　・Launches barrier bits linked to the Mega Beam Shield. 　　　　After the weapon is used, barrier bits are deployed, 　　　　with enemy ranged attacks negated by a triangular I-field. 　　　　Tackling power is also significantly enhanced while deployed, altering reaction to tackles 　　　　so that enemies that are not toppled or under a status effect can be knocked back. 　　　・Reloading, taking a melee attack, or triggering a counter 　　　　while barrier bits are deployed will release the deployment. 　　　　If your unit pulls off a counter disabling the barrier bits, the Heat Gauge will fully recover.
