No. We find somewhere to hide
sandbag sandbag sandbag sandbag + 2 explosive blocks, we call them block3s. set up the detonator, set up the detcord, run to hiding spot, at least 50m, behind cover, and press the button!! Nothing fancy, just a button that detonates the detcord. The detcord sends a detonation wave to the block3s,
BOOM. exercise cut!
you can stagger the detonation order by varying the length of the detcord, i can't remember the rate of burning now though. been ages..
