Situational Awareness - Kieranator/BadArma GitHub Wiki

Staying alert is a top priority for everyone. Most basic concepts have already been mentioned or explained elsewhere, like covering sectors and dangerous areas, scanning for enemy at all times, listening, and keeping track of friendly positions via the map.

Primarily, you want to spot the enemy before they spot you. Actively avoid tunnel vision, in and out of combat. Pay attention to the bases of trees and bushes, any hard cover like rocks, walls, or structures, especially tall or dominating structures. Beware windows, doors, stairwells or other superstructures on rooftops, and keep an eye out for flattened bushes and felled trees from a vehicle's passage.
