Goro (Pre Bugranger Equipment) Tear Gas and Gasmask.

Lieutenant 1st class Goro Aori of the JSDF stood outside a closed door in a crowded tenement complex, gun raised, perfectly still and silent. On the other side of the door, crouched low to the ground was another soldier, staring through the closed door using his thermal goggles.

After several moments, he lowered his goggles, nodded at Goro, and held up two fingers.

Goro nodded and turned to the captain, standing with the rest of the squad a little ways down the hallway, guns pointed at the door. He nodded and flashed two fingers.

The captain nodded back and made a hand signal to advance. The squad parted, and two soldiers trotted forward, carrying a battering ram between them. The captain gestured to them, then at the door, then at Goro, who quickly took out a teargas grenade, priming it to throw.

The captain nodded once, and the soldiers carrying the battering ram rushed forward and slammed it into the door, knocking it off its hinges and startling the two individuals seated at a table in the filthy apartment inside. One of them was dressed like a politician, while the other was dressed so much like a stereotypical Eastern terrorist one could be forgiven for assuming he was into some really disgusting cosplay.

On the table were two briefcases, one of which was open to reveal several million yen. The other was closed, but Goro already knew from the briefing that there was something much more dangerous inside.

He threw the teargas grenade into the room and pulled on his gas mask as he, and his similarly attired squad mates, rushed into the room, pointing their guns at the criminals, who were coughing and choking as smoke filled the room. "JSDF! Nobody move!" The captain bellowed.
