Javelins do have use in the early game, and there are many deployments that pit you against (or even alongside) the 10A with its LRM15. Salvaging that platform finds an energy hardpoint in each arm, two missile points in one torso, and two support in the other. Here's my favorite way to use this run-and-gun platform. First is the one I feel is most optimized: the SRM+SL harasser. On approach, 10 SRMs can help you whittle down enemy armor and evasion while spotting for your slower medium mechs. Then, jump or maneuver into an enemy's rear and shred them from behind. Just keep this mech moving, because it still has light armor. Adjustments: sacrifice .5T armor for one more Jump Jet to get real maneuvering for behind-the-back attacks. Pros: Far more survivable than stock with a 520 armor rating, SRM ammo for 10 rounds, decent heat management, SLs make melee an option, two shield arms! Cons: Damage on approach is not fantastic, wants another JJ. Shown using standard equipment. By the time you get + or ++ equipment, you'll want it on a heavier mech.
