The red Gundam tossed the rifle aside while dodging to avoid the strike from Kuroda's lance, pulling out it's beam saber to get in a quick stab at one of the break's shoulder joints before it retreated backwards regardless of rather or not the strike connected to give itself enough time to get out it's main melee weapon, the large blade at it's side. If the beam saber stab connected, it would leave the blade in the Break Gundam's shoulder joint while it retreated, and if it didn't connect, the red Gundam would have to take a few more seconds to put the saber away before pulling out the katana. Either way it would likely have enough time to get the weapon out now, due to it's superior speed over the Break.
