When Captain America throws his mighty shield! Well, it seems that the shield is now very useful tool for airsoft events as this chap did during Godfather Airsoft's Apocalypse Now event that was held at the GF Club. Tactically, that shield is a big "shoot me" thing, but if distracted the enemy's attention to it, and giving his mates a clear way to their objectives, then it had done its job.

All those who chose to oppose his shield must yield.
If he’s led to a fight and a duel is due,
Then the red and white and the blue’ll come through
When Captain America throws his mighty shield.
