After Reviewing the evidence i have decided to Deny this report
About event rule 1.1 , Teaming up is a different thing according to evidence they were at same locations at different times , teaming up is when they are not killing each other and working as team to kill you ( which didn't happen in this case ), they were camping bush at totally different times .
and about the tracers part , its allowed to remove tracers as that does not give you any advantage , messing with tracers only gives you advantage when you increase the opacity / thickness of tracers so it guides you the direction from where gunshots are coming .
