 The Partisans'strategy was based around mountain-based guerrilla warfare, in which they took refuge in the mountains and launched raids into the less defensible lowlands. By contrast, Hoxha aimed to defend Albania's national integrity and sovereignty "at all costs", which necessitated defending the lowlands as well. The bunkers were therefore intended to establish defensive positions across the entirety of the country. Smaller ones were laid out in lines radiating out within sight of a large command bunker, which was permanently manned. The commanders of the large bunkers would communicate with their superiors by radio and with the occupants of the smaller bunkers by making visual signals that could be seen through slits.
