Captain America: Civil War trailer "“ a closer look

You can insert the Ken Watanabe gif with let them fight, because Captain America: Civil War seems to be all about that. We still didn't figure what exactly would make them go all out against each other (it cannot be just a simple idea"¦), but, boy, we are excited!
But, as you will see, there are also some other types of scenes, with characters such as General Ross and the mysterious one played by Martin Freeman.
The Captain America: Civil War Asia Pop Comic Con trailer opens with the scene from the African market, which is presumed to be the one to trigger the Registration Act. As described, the scene switches from Redwing (which flies under a van filled with explosives), to Captain America (ordering the attack), and Falcon dropping from atop a building and opening his wings only in the last moment, before hitting the ground.
Crossbones is the leader of the HYDRA soldiers from the market and he fights with Captain America. He throws a sticky grenade, which attaches itself to the shield "“ Steve throws it away, but still flinches when it explodes in the air. At this moment, Crossbones attacks from the back "“ but is (apparently) subdued pretty easily. After his gauntlets are torn apart, he produces a blade with which he attacks the hero. In the ensuing fight, his helmet is cracked open.
Black Widow also appears in this opening scene, doing her signature move (the one with which she impressed in Iron Man 2 "“ the leg wrap).
