MOLLE is a latter locking attachment system, more commonly referred to as “basket weaving.” You take any pouch place it where you want it and begin weaving the straps in and out. If you have pouches with tuck tabs (also called soft snaps) once there is roughly 1.5 to 3” inches hanging out, you will tuck the plastic tab back in under itself locking it into place. If you have an older style snap system there will not be any excess length. You will simply weave the 1” strap until you can snap it down. The video below give you a good look at how both systems work:
