The problem is that the ground-based aspect of the Federation's military is never depicted in the show or elaborated on in the supplementary materials. This is due to a combination of the show's focus on idealistic, character-driven exploration and adventure, and basic budget limitations. The latter also means that when ground troops were shown in the shows, they were usually just redshirts with no costume alterations.Xan Krieger said:I know my W40K stuff but could someone please teach me about Star Trek's ground based warmachines? What is their answer to the armored regiments of the imperial guard and titans of the adeptus titanicus?
It might be safe to guess that they primarily use teleporters or at least shuttles for terrestrial transport - mostly negating the need for tanks or ATVs - and rely on space warfare for nearly all military operations. This is the inverse of the Imperium, which puts the most focus on the ground combat, with the naval aspect being relegated to supplementary fiction or Battlefleet Gothic.
In general, I would expect Starfleet to be at an incredible disadvantage when forced into ground combat. Their best assets would be teleporters. So they'd have the maneouvre advantage, but their ability to actually do any damage would be limited to sabotage and ambushes.
