Secondly, weather has an adverse impact on force protection because rapid reaction of ground reinforcements is inhibited. Obviously, there is no confrontation line between NATO forces and the warring factions. NATO is not going to Bosnia to pick a fight. However, there is a high probability of hostility at the local level over the location of the entity boundaries, property ownership, acts of atrocity, etc. The frustrations and anger may well be vented on the NATO forces.
Revenge is a strong motivation in the Balkans and use of force is the norm.
For any commander, the worst enemy is one who is an unknown quantity with unknown intentions while operating in his own back yard with local support. Terrain presents the military commanders at every level with formidable obstacles made worse by adverse weather. Bosnia is mostly heavily wooded and mountainous with steep slopes coming down to roadways. Main roads often follow river beds bordered by rock cliffs and interrupted every few miles by bridges and tunnels. Secondary roads are frequently no more than narrow forest trails without all-weather surfacing and, at high altitudes, impossible during the winter.
