NPC’s ability to spotting bugs, assault rifle squads all six NPCS can be a person with melee kill without resistance
meaning what? 
Looks like google translate - perhaps meaning the AI is unprotected against melee currently, all six get killed by single enemy?
I think what he meant was something like: “Even if my entire squad constist of Mp-Soldires, the npcs can still easily be killed by single guy rushing them to melee kill them.”
