This mod is a simple mod. It adds 3 type of additional bombardment stance. Precision, Strategic, Xenocide bombardment stance. Precision is specified to enemy army, and a little damage to tile and pops Strategic is specified to destroying enemy planet damamg and little damage to army and pops. Xenocide is specified to kill the pops. This stance stops when kill are enemy pops on planet. and army has moderate damage, tiles are safe. This stance can use when you research Bombardment Doctrine (society tech). This is 3 tier tech and you must research military academy tech before. ---------------------- 2018. 10. 19 Ver. 1. 0. 1.
