Steel Bastion

From publisher blurb:

As the war in Europe rages on, the need for a strong and well-trained Aegis presence in Italy becomes paramount. The Aegis Initiative has launched a clandestine operation to establish a new squadron deep in contested territory, forming a strike force to counter the growing influence of the Shadum Collective. You have been assigned to recruit, train, and lead this elite squadron, forging a force capable of disrupting Shadum's shadowy operations in the region.
