Is a squad of Space Marines stronger than a squad of Fire Warriors in Warhammer 40000?

Answer 1

This depends on the size of the squad, and in what scenario they are. If it is 1 Space Marine vs. 10 Fire Warriors, the Marine doesn't stand a chance and vice versa.

Also, Space Marines are better all-rounders where as Fire Warriors are excellent long range firepower troops. At range the Fire Warriors should come out tops, but at short range and close combat the Space Marines would crush the Fire Warriors.

On a point by point basis, the average Marine is worth 16 points, and a Fire Warrior is a worth 10. So if the squads are equal in number, the Space Marines are technically a stronger squad.

Answer 2

In official warhammer lore, each space marine is more than a match for ten or more orks, but in the videogame adaption (highly recommended), you can easily chew your way through mobs of 30+ orks.
