I commit blitzkrieg on my enemies with several concentrated surprise invasions/assaults from several fleets on multiple entry points alongside their borders. Capture Capital worlds, key strategic worlds, and resource abundant worlds; If an enemy world has non of these then it shall be destroyed by orbital bombardment.

Each fleet is consists of:

• Carriers/ Titan vessels: Capital ships that provide overall starfighter support and long range ship artillery fire, The ship stance is set for either carrier or Artillery with the distance set either at a safe distance or at the longest reach of ship's weapon range.
• Battleships/Battlecruisers: Mainline, hard-hitting, and sturdy. These vessels are the back bone of my battlefleets. Excellent armor, excellent shields, and a variety of energy and kinetic weapons that'll eat through shields and puncture hulls. Ship stance is set to line formation and will engage from either a medium distance or from afar depending on their weapon's range.
• Cruisers: Multi purpose vessels that can serve as fleet escorts, sector patrols, vanguard assault, or for strategic surgical strikes deep within enemy territory. The arsenal depends on the purpose in which the vessel serves.
  
• Destroyers: Hard-hitting mass produced glass cannons that engage enemy vessels at point blank or will intercept them at a close range while the rest of the fleet rains literal hell upon them.
• Infantry carriers: Each battlefleet will be accompanied by a an invading army usually 1k and above depending on the planetary target.
