TDR-7M Thunderbolt
http://www.sarna.net/wiki/images/2/29/TDR-Thunderbolt.pngUpgraded with Star League technology, the 7M has been re-armored using Ferro-Fibrous armor, reducing the weight of the armor to eleven and a half tons. The saved weight has allowed the 'Mechs arsenal to be upgraded as well. With an arsenal based on the 5S model, the 7M carries an LRM-15 missile launcher, an ER Large Laser, three Medium Lasers, a Streak SRM-2 launcher, and a pair of Machine Guns. Additionally, the heat sinks have been upgraded to double heat sinks and CASE has been added to protect against ammunition explosion.
While the more expensive ferro-fibrous armor would be more difficult to replace in a pinch, it also remains serviceable with less advanced systems. Even if the mech were mauled and every weapon system destroyed engineers could repair and refit it with standard versions of weapons and equipment which would also free up the necessary weight to bring the armor levels up to snuff. CASE ensures that the mech won't get blasted in half by a lucky hit, further prolonging its life and its lack of an XL engine means it will still be able to fight on with at least 50% efficiency.
LRM-15 gives it long range direct and indirect fire capabilities as the mission requires
ER Large Laser gives it good long to short range heavy direct fire capabilities, no ammunition concerns
3 Medium Lasers gives it great short range firepower again with no ammunition concerns
SRM-2 streak is highly efficient, only firing when it has a lock and makes for a great crit seeking backup weapon and vehicle hunter
2 Machine Guns can cut infantry apart and discourage any enemy from getting too close
At 65 tons and with 2 functioning hand actuators, the Thunderbolt can uproot a tree or pick up a severed limb and crack open an enemy cockpit with a single blow.
At 65 tons a kick from the Thunderbolt can sheer the leg off of most light mechs with a single blow.
At 65 tons and 64kph, a full on charge from a Thunderbolt will destroy roughly 2.5 tons of armor from the recipient of the charge.
