Fieldcraft is the techniques involved in living, traveling, or making military or scientific observations in the field and the methods used to do so. The term "fieldcraft" is used in a broad range of industries including military, oil and gas, wildlife and food and agriculture.
In the anti-terrorism field, field craft is defined as "the art of evading monitoring by police and the security services." Terror groups such as the one tracked by Operation Guava were caught "despite their own well developed field craft."
Field 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 memorizing battlefield details, infiltration and escape routes, construction and employment of hiding positions, enemy force doctrines and equipment.
