No way any these can take space marines. In horus hersey novel they fight a human race with armor like astartes but they were just human. It was a slaughter. 40k for space marine s are to strong. Like terminator armor. The dreadnought that has astate in it. Not including the ships or Titans. The jedi couldn't fight off clones. Clones are just human. Covenant just don't have strength or fire power. They can't even handle master chief lol. Astartes are way more advanced and guns would cut through sheild and armor like paper.
