About Close the strait !
The strait is narrow. The oil routes are vital. And the enemy is already on the horizon. You command the defenses of a strategically critical maritime passage—the lifeline of your nation’s economy. Every tanker that crosses these waters carries precious oil, and every barrel that reaches safety strengthens your war effort. But the strait has become a hunting ground. Pirate fleets, raiders, submarines, aircraft, and increasingly powerful enemy formations are moving in to seize your resources and break your defenses. Your mission is simple: Protect the oil. Hold the coastline. Close the strait. BUILD YOUR DEFENSE Every operation begins with limited resources and an exposed coastline. Deploy machine-gun positions, anti-ship batteries, missile systems, radar installations, anti-air defenses, artillery, mines, and fortified positions across strategically important locations. But static defenses are only the beginning. As the battle escalates, you'll gain access to a growing military arsenal: Tanks & Armored Units — Reinforce vulnerable positions and intercept enemy landings. Aircraft — Launch fighters, interceptors, bombers, and strike missions against incoming threats. Naval Forces — Deploy patrol boats, missile craft, destroyers, and other vessels to control the waters. Submarines — Hunt enemy fleets from beneath the surface and strike before they reach your defenses. Radar & Reconnaissance — Detect distant threats and give your defenses the information they need to respond. Missile & Artillery Systems — Destroy high-value targets before they can reach the strait. Every unit has a purpose. Every emplacement matters. And every weakness in your defensive network will eventually be tested. DETECT. IDENTIFY. DESTROY. Firepower means nothing if you cannot see the enemy coming. Build a network of radars, reconnaissance systems, observation posts, and detection equipment to expand your battlefield awareness. Enemy aircraft can approach from beyond the horizon. Submarines can slip beneath your defenses. Fast attack boats can exploit gaps in your coverage. Different threats demand different answers. A radar station might detect an incoming bomber formation—but you'll still need the ammunition and weapons capable of bringing it down. A sonar system might reveal a submarine—but detecting it and destroying it are two very different problems. As the enemy grows stronger, building the right combination of detection, range, firepower, ammunition,…Read more
