"How is a Bulwark like your mother?" -last words of Bernie Lovell, Nimbian comic.

The Bulwark is a damage-absorber. Set it between a valuable unit and hostile fire. The attacking unit will retarget to attack the Bulwark.

The Bulwark is the toughest building in Nimbus. It is utterly invulnerable to air assault, and very sturdy against ground fire. The Bulwark sucks up damage like a sponge, but it is not cheap.
