You did NOT initiate on the hemmet (car people) you just opened fire, secondly yellow tracers is hard to see in daytime, third regardless of Mk20 or Spar they are both 5.56 WITH TRACERS,
i always keep a vermin in my bag, i had thrown the spar in the vans inventory, i also used YELLOW tracers
you guys also attacked us with the people in the other copter and cars without initiating
