[[File:Evt ground combat.png|330px|right|thumb|Although secondary to space battles, ground warfare is a vital aspect of many wars.]]
Ground combat takes place between the planet owner's defense armies and the invader's assault armies. The number of armies that can be engaged in combat on either side is five plus one-fifth of the size of the planet. Armies not engaged in combat will be placed a row behind the fighting armies and replace any killed army.

Generals are leaders who command armies and give them bonuses. However Generals have a 5% chance to die whenever one of their armies is killed.

Each army has a morale value, and once morale drops low enough the army will be negatively affected with the following modifiers:
{| class="mildtable" style="text-align: center;
! Morale
! Penalty
|-
| 50%
| {{red|−25%}} {{iconify|Army damage}}
|-
| 0%
| {{red|−75%}} {{iconify|Army damage}}
|}

Armies gain experience from combat and can rank up. Higher rank armies are more effective in combat.

An attacker can always attempt to retreat. However there is a significant chance that each retreating army is destroyed while attempting to return to space, making retreat a risky endeavour and something to do only in very poorly chosen engagements.

=== Planet devastation ===
Planet devastation is a measure of how much damage has been caused to the planet's population centers. It goes from 0 to 100% and the higher it is the more damage defensive armies take and the more likely pops are to be killed. Every 1% planetary devastation causes a 1% decrease in {{iconify|Housing}}, {{iconify|Amenities}}, {{iconify|Trade Value}}, {{icon|pop resource output}} Resources from Jobs, {{iconify|Upkeep}} from Jobs, {{iconify|Growth Speed}} and {{icon|migration attraction}} Immigration Pull.

Planet devastation is caused by orbital bombardment and assault armies. Assault armies have a '''Collateral Damage''' modifier that determines how fast they cause planetary devastation. Defense armies do not cause any.

Planet Devastation recovers by 0.05% daily if planet is not being invaded or bombarded.
