Overview:
The Thorn is an older BattleMech design, incorporated into the Hegemony Armed Forces during
the late 24th Century. It was the first 'Mech to incorporate the Endo Steel II Skeleton. The
Thorn was unveiled with tremendous hype, but initial reviews were mixed. Commanders later
agreed that Endo Steel II had obvious advantages but would not be suitable for all 'Mechs.
The Thorn was designed to serve in front-line combat units. Its inability to jump was
not considered unusual for this type of duty, but commanders who tried to use all light
'Mechs as scouts found the Thorn to be useless. Once seperated from company mates, the
Thorn's heavier armor and greater firepower were no match for a quicker opponent.
Capabilities:
The Thorn has had mixed reviews for the entire length of its service. Supporters point out
that the design packs more punch per ton than any other 'Mech and that its armor is also the
best of its size. In a toe-to-toe slugfest, the Thorn can usually reduce an equal weight
opponent to scrap in minutes.
Opponents of the design note that a 'Mech cannot hit what it cannot reach. Although the
120 Class engine allows the 'Mech to run at a respectable speed, its lack of jump jets
leaves the Thorn in the dust of other light 'Mechs. The Zeus Long-Range Missile system only
partially offsets this lack of pursuit ability.
This favoring of armor and weapons over maneuverabilty has made the Thorn a favorite of
front-line light companies.
The weapon placement and ease of maintenance have given the design high marks in every
technician's manual. The arms and legs are completely accessible, allowing a service crew to
actually enter the limbs and work on repairs from the inside.
The Thorn's main armament consists of twin medium lasers. These identical weapons
further imrove maintenance and are extremely efficient. The design is noted as a "cool
running" 'Mech, but the placement of one laser directly under the pilot's feet makes the
Thorn seem to be running hotter than it really is. Extensive cooling is provided in the
cockpit area, but the lack of an effective venting system for the medium laser makes
repeated firing uncomfortable for the pilot.
The Zeus Long-Range Missile system is extremely accurate, and the arm mount allows the
pilot to switch targets quickly. If damaged, the entire system can be replaced in a few
hours, which is fortunate as the launcher can easily be destroyed if the 'Mech engages in
hand-to-hand combat. The missile-feed system, which passes reloads from the torso storage
compartment, is average at best. If damaged, reloads can become lodged in the upper arm,
where additional damage has been known to cause detonation, destroying the arm.

I have to agree with Nightrunner here. This was constructed even before the hightime of the Star League: The first Mech incorporating CASE (as i remember). The CASE and full armor makes this a tough target for a 20tonner. It suffers still from the standard speed/no jumpjets combination but in a battalion in can be of good (not excellent but good) use.

Full armor, standard speed and far reaching weapons. This thing was probably meant to face conventional units, which were largely defenseless against LRMs and unable to close on the Thorn (of course that vees can do it, but there are two MLs and lance-mates). The Thorn is good when facing similar weight opposition or conventional forces. When something stronger moves in, the Thorn should be somewhere else or well covered.

You really have to look at this one in context- it's not a new 3050 mech, it's an old Star League mech about five centuries old. It predates double heat sinks, the Clans, and other problems modern lights face. At the time, it was a rarity- a 20 ton mech with LRMs- and any light that dropped below minimum range has to face 2 medium lasers. At the time, ER weapons didn't exist; LRMs were the longest range weapons commonly availible.
So with more firepower than anything else in its class, and enough speed to keep out of the way of heavies a lance of these would be quite an asset to Star League forces. The Thorns the Com Guards pulled out of storage are less useful against Clan forces, but it is a tough little bugger; it can be useful if part of a larger group.

Take out the lrm's and add a little more armour and a 4 MG's and you will have an excellent city fighter would give this mech a 4 if that were to happen

Not a very useful design unless your a House Marik Commander looking to kill off rival mechwarriors by giving them the honour of piloting this machine.
Its too slow to be a 20 tonner. Too lightly armour and short ranged to be a medium Mech.
Its like a size 2.3459 boot. nobody can wear it but boy does it shine nicely in garrison.
