In political science, a proxy war is as an armed conflict fought between two belligerents, wherein one belligerent is a non-state actor supported by an external third-party power. In the term proxy war, the non-state actor is the proxy, yet both belligerents in a proxy war can be considered proxies if both are receiving foreign military aid from a third party country. Acting either as a nation-state government or as a conventional force, a proxy belligerent acts in behalf of a third-party state sponsor. A proxy war is characterised by a direct, long-term, geopolitical relationship between the third-party sponsor states and their client states and non-state clients, thus the political sponsorship becomes military sponsorship when the third-party powers fund the soldiers and their matériel to equip the belligerent proxy-army to launch and fight and sustain a war to victory, and government power.

Conventional warfare is a form of warfare conducted by using conventional weapons and battlefield tactics between two or more states in open confrontation. The forces on each side are well-defined and fight by using weapons that target primarily the opponent's military. It is normally fought by using conventional weapons, not chemical, biological, radiological, or nuclear weapons.
