Do i put a capital on Xenomorph, if i say someones rank like Corporal Dwayne Hicks is their rank part of the link to their page or is it just their name that i use for the link, and if i say Hicks's is the 's part of the link to their page?

Also if i say a Xenomorph type like a Warrior would Warrior have a capital? And flamethrower dose not take a capital right?
