FieldCraft, founded in 2001, is an Australian information services business specialising in general research, project management, software development, standards compliant web development, and geological services including sedimentology, petroleum geology, well site geology, and drilling rig supervision.
Fieldcraft is the tactical skill to operate stealthily and the methods used to do so, which can differ during day or night and due to weather or terrain.
These skills include camouflage, land and water navigation, understanding the difference between concealment from view and cover from small arms' fire, using the terrain and its features to mask ground movement, obstacle crossing, selecting good firing positions, lying-up positions, camping positions, effective observation, camouflage penetration, countersurveillance, detecting enemy-fire directionality and range, survival, evasion, and escape techniques.
Good fieldcraft is especially important for the effectiveness and survival of infantry soldiers, snipers, special forces, reconnaissance and sabotage teams. Efficient fieldcraft is only possible by spending time, effort, and attention to memorize battlefield details, infiltration and escape routes, construction and employment of hiding positions, enemy force doctrines and equipment.
