What am I missing for this field research challenge....to kill 2 hostiles with 1 grenade 3 times...I have managed it once but I don't know how I did it and can not for the life of me manage it again although nothing in my set up has changed and I am often seeing 2 or more hostiles burn to death from 1 grenade.
I am now resorting to all kinds of ways to achieve this (i.e holding them in place with chem launcher riot foam stuff then hitting them with a grenade or softening them up a little with pistol shots then hitting them etc)...nothing seems to work.
I MUST be missing something totally obvious here so any tips would be appreciated guys.
Regards
