Welp, time to resurrect this thread with regards to the three new variants derived from Recognition Guide 17.
First up is the 5, derived from the XR. It mounts four Clan RAC 2s, two per arm, with an ER Large Laser and a pair of LRM 10s as backup weaponry. And also an ECM suite, which is a bit of a rarity in Rec Guide designs.
Second is the 6, which is the WYSWYG variant that mimics the standard. But it does so by using ten Protomech AC 2s. Saves weight, but at the expense of range and the ability to double-tap. It does, however, have the ability to use specialty munitions, and with six tons of ammo there's ample incentive to do so. It also uses the weight savings for using the smaller guns to replace the original's four machine guns with four ER Medium lasers and hooks all the weaponry up to a targeting computer.
Finally, there's the 7. And it's a complete monster. It keeps the quad ER mediums from the 6. It's also got a large laser, though unlike the 5 it uses a Large Pulse Laser instead of an ER model. It doesn't use autocannons of any kind. It uses a pair of HAG 40s, one in each arm, fed by 12 tons of ammo. This mech is going to cause pain.
