|This unit has no upgrades. This means that this unit can not gain any sort of permanent boost from upgrades found in either its palantir or from other units/heroes. If this is not the case, fill in the section following the policy.|
As a heroic unit, Caras Galadhon Guards are good vs everything as long as you keep them out of melee fight. They can't receive any upgrades, but the ability Thorn Arrows works similarly to Silverthorn Arrows. Since Caras Galadhon Guards have a lot of prerequisites, you can only gain them in the late game.
