Jeeesze, just go to the gate and muscle yourself over.
Or find a hole.
Bringing ladders shows intent, is a pain, is unneeded, and just a basic lack of style unbecoming of a seasoned explorer.
Always choose your breaching point wisely...
The most dangerous fence to breach is an unstable one even if it's just chain link. I've gotten hung up like that with the top wires stuck in my pants... it can be hard to get off when you're using both arms to support yourself and the fence is not staying still
Yes you could easily end up with a ripped nut sack or thigh if you don't stay chilly or are a weak sucker. At the best you'll just have a hole in your pants or a ripped out pants leg. I ended up pushing off after being hung up for over a minute and landing on my back, intact, on the other side... don't get too clever for your own good!
Always breach fences were they're stable preferably by a tree, telephone pole or other object to aid your climb/stability, at a gate or in a corner section. At the top pay close attention to not getting snagged on a barb(s) or wire. Take your time and do it right.
Don't leap down; climb down.
Throw your gear over, don't climb with it unless you're strong enough to and it's strapped to you high and proper.
Avoid razor wire, an entanglement with it can be fatal.
You need to be fit. At the minimum able to do at least 10 body drips and 6 chin ups. Otherwise you're shit's going to be weak especially if you run into trouble.
