After opening the game Clash of Clans, you will have to use your Laboratory to upgrade troops. This is the only way to level up troops in Clash of Clans.

The Laboratory is a building which can be built at Town Hall level 3, and it costs 25,000 elixirs to build. Once you have this building, tap on it. You will have at least two options: Info and Research. You may have Upgrade depending on your Laboratory Level.

Level up troops steps

To upgrade troops, tap on Research. This opens a window where we can view all the upgrades the laboratory has to offer. Depending on the number of troops you have unlocked, you will be able to view the upgrade requisites of those troops. This window contains both elixir and dark elixir troops, as well as the same for spells. A recent update to the game has added Siege Machines to the game, you can also upgrade those here for the elixir.

To level up troops, locate it by its image on the window of the laboratory. You will find that it is a colored image if you have enough elixir or dark elixir to upgrade it, otherwise, it will be in black and white. Even if you don’t have the required amount of elixir or dark elixir, you will be able to view the details of the upgrade for the troop. However, if you have not unlocked the troop yet by upgrading your barracks, you will not be able to view its details. The image of the troop will be faded and you will not be able to tap on it.
