In the movie Terminator: Dark Fate, the character Grace instructs Sarah Connor on how to lay mines. This action is crucial for their survival, as they need to prevent the Rev-9 Terminator from reaching its target. The mines serve as a defensive measure, creating a barrier that the Terminator must navigate through, slowing it down and giving Sarah and Grace a chance to escape.
Laying mines is a strategic tactic that has been used in warfare for centuries. It involves placing explosive devices in the ground to detonate when pressure is applied. In the movie, Sarah Connor uses homemade mines constructed from propane tanks and nails. These mines are effective in damaging the Rev-9 and hindering its pursuit.
