The M60A1 Minuteman class moonbase-compatible light mech can dock with a moonbase via an endcap.
About this creation
The M60A1 MinuteMan is a light humanoid mech which can dock with a purpose-built moonbase-compatible endcap. The endcap recharges the mech, transfers a pilot into it directly from the moonbase, and acts as its armory. The ability to transfer a pilot directly into the mech from a pressurized corridor improves launch time compared to forcing the pilot to do an EVA or launching the mech from a pressurized mech bay. As such, anything that requires a fast response time is likely to be found in this mech's mission profile, from fire fighting to first-response moonbase defense. The moon also provides an ideal environment for the operation of mechs. Low gravity makes for easy walking, rough terrain means tough driving for traditional vehicles, and the lack of atmosphere complicates the use of infantry.
This mech (including the endcap, mock-up corridor, and some of the weapons) took less than two weeks to build, but I've been tinkering with it for the better part of a month making minor improvements and extra weapon systems. The biggest thing I'm still not satisfied with is the absence of a spine joint that allows the torso to tilt and swivel independently of the hips. The spine would have occupied a space where the docking hatch wound up in the final design. Simply inserting a spine joint would have offset the proportions of the mech and made it too tall (even when kneeling) to dock with the endcap. I could bore you with more construction details (don't think I can't! I could if I wanted to!), but instead I am just going to give credit to the people and designs who helped me out along the way and let you get to the pictures ^_^ .

The mech is powered by a series of high-density power cells: one large unit on the chest, two smaller ones on the legs. These limit the MinuteMan's range, but are faster to start up and safer to keep fully fueled than traditional reactors.
The hands on this mech are not particularly accurate to a human hand. I was more concerned with a wider grip for holding more weapons. Also, the technic pin holes on the hands act like hardpoints to plug in to the long-range KE cannon and gatling cannon.
Assorted missile launchers. On the arm hardpoint: L/H Series 1 Combo Launcher (Laser-guided and heatseeking).
On the hip hardpoints: GREV-8 SFW (reverse-engineered from captured sensor fused weapon of 3vil manufacture).
The Chemidyne Industries wide-field building sealant distributor is used to fight fires and seal small leaks. I tried to make the tank on the back hardpoint look like the life support tanks carried by modern firefighters. The system also includes a pump mounted to the forearm hardpoint and a pistolgrip nozzle.
The small thrusters on the legs are permanently mounted. When combined with the optional GE space systems high-yield space maneuvering thrusters on the shoulder hardpoints, the MinuteMan can reach significant altitude. What these thrusters lack is the endurance for true flight. A few jumps is all the pilot will get without external tanks or refueling.
The PhysicsMancer Bass Mk. 3 from Fender Gnarworks (Fender's secret R&D department) generates a short range, wide field force field that vibrates the hulls of enemy vehicles. In its heyday, only a few were issued to skilled pilots and squad leaders. You have to play a lot of Guitar Hero and watch a lot of giant robot anime to come up with this.
What? You've never seen a mech with a guitar before?
The first an only time it was used in combat was against the contents of a Starbucks invasion force heavy dropship. Eyewitnesses reported that the enemy mechs exhibited "moshing" behavior before destroying themselves. The pilot's debriefing revealed that he had whipped out a "wicked awesome" heavy metal bass solo. Shortly after, strict limits were placed on its use against sentient beings. This is the only technology currently in the arsenal of Moonbase Defense known to be effective against Mark Stafford's Cute field projector technology.
