What advantages might a weaker army fighting on its home soil have over a stronger invaiding army?

Answer 1

From my experience in Iraq they will have the following: 1. Knowing the routs - very important strategically. 2. Local nationals support. 3. Recruitment of new units. 4. They spend much less money on war. 5. Motivation and moral boost.

Answer 2

A weaker army fighting on its home soil may have advantages such as knowledge of the terrain, support from local population, supply line advantages, and the ability to use guerilla tactics effectively against the invading army. These factors can help offset the strength disparity between the two armies.
