halo reach campaign on legendary tips

playing halo reach on legenday can be a diffcult task for any one.
but to make things easier i have tips. the elites can be hell but luckly. for you the key to beat them is the grunts/the grunts
usually carry plasma pistols or fuel rods. but when ever you kill a grunt pick up their plasma pistol.
and charge it until it glows green(keep in mind you need a dmr or needle rifle for this to be succesful) and shoot it at a elite if hit their shields will drop and all you need to do is follow up with a headshot.
any more question pm infamous.
