Yeah, we did something similar.
We needed to get into a place, and back out.
Getting in we figured would be easy enough, but getting out...
Since none of us had demolitions skill, and my character was a sort of almost-fixer type, the others just told me to get some explosives and plant the stuff.
My character then bought 2 satchels of C12, with detonators rigged up by someone who knew how, and put one at the base of each of 2 pillars, holding up the fence.
I'd expected reinforced concrete pillars mind you, so I'd maybe overdosed the amount of C12, just a tad...
What we got included 2 holes in the ground, large enough to present sever difficulties to jeeps. But atleast the fence went away, and we put a bit of a distraction of the sec.goons.
