When I was still in the Army I was taking out the trash to the dumpster about to go home for the day, walking right behind another formation of soldiers, about 115 of them. I threw the bag in the dumpster and slammed the lid shut. 

A swarm of bees I would describe of extremely densely packed, 20 foot blob like something out of the John Constantine movie came flying out directly at us. 

Right as it happened, the guide-on bearer at the head of the formation noticed what happened, and at the top of his lungs, yelled “BEEEEES”!! And pointed. 

116 Scouts, most of which combat veterans, myself included, running and screaming like little bitches in every direction, about 100 ft away our sister troop laughing their asses off. 

You don’t fuck with bees.
