The man in camouflage pants telephones 911 for the man in black sneakers who is lying on the ground having a heart attack.
The men are terrified.
The men may be relaxed or trained in this situation, calling 911 doesn't indicate panic.
Although the man is calling 911 and the other is having a heart attack, it does not mean the men are terrified.
Just because a man is wearing camouflage pants and calls 911 does not mean he is terrified.
