The actions of the Jieke Group shocked the world, and Siam was especially thrown into utter chaos.
The Jieke Group, having just annihilated the Chan Country Government, was at the peak of its military might. Such a fearsome force, combined with the presence of the Steel Camp, put immense psychological pressure on Siam with their massive army stationed at the border.
Although the Siam Navy was powerful and the Air Force held an advantage, their Army was severely lacking, with only 200,000 personnel and outdated equipment.
Moreover, like Chan Country, Siam also has numerous mountains and forests within its territory.
In such environments, the effectiveness of the Air Force would be greatly limited, whereas it became an ideal battleground for guerrilla warfare by ground forces.
