grenades or airstrikes had some initial delay before damage got applied to target
right now you perform attack on target and it gets instantly damage. animation then starts like throwing grenade and then you see explosion. so delay is not active atm

take a closer look into combat_data.iff:
initialDelayAttackInterval: if -1 it gets ignored like buffs or melee attack (of_decapitate_x)
delayAttackInterval: here you can see the seconds the attack will be delayed
