4. Once you destroyed everything except the archery, the AI will only build archers.
5. Use your Sipahis to kill them of after spawning and them have them retreat. (this way they dont kill off the archery

Start a Skirmish or Multiplayer game as the Ottomans. Doing this with a boosting partner will make it very easy but it is also doable with an AI set to easy. After the game started advance to AGE II to unlock the Stable.
Sipahi are cavalry units made in the Stable so build a couple of them.
Simply keep producing Sipahi units and use them to kill any ranged units that the AI or your boosting partner produces.
After killing 100 ranged units the achievement will unlock after the game has ended.
