If the mecha was small, but armored in the front, they would only be useful in one situation: in doors combat. It would be the only armored unit to date capable of maneuvering in enclosed spaces. Tanks and jeeps can't go inside if it's needed. Of course, the mecha would still have several flaws. Such examples being hand held explosives (grenades) and tight passageways. Still, it may be the only option if you have an enemy who has fortified themselves in an inaccessible portion of a building and you need to get through a soldier bottle neck barricade, or any other form of in door combat scenario. One thing the mecha would need is foot soldiers as support. If it goes in by itself, it could be easily flanked and destroyed. By sending in one mecha per platoon, you would increase it's effectiveness ten-fold.
Nah. Mechs need to be armoured all over for indoors combat. Even moreso as there isn't much room to manuever and dodge. And since the mech must be small enough to be used indoors, there would be only one operator. Even then, the mech would be less suited to indoors combat and more suited for urban combat. Power Armour (think Halo or Starship Troopers) is more suited for indoors combat.

Outdoors (both urban and non-urban), most of the armour would be devoted to protecting systems vital for the operation of the mech and safety of the operator(s). A lesser proportion of the armour would be dedicated to limbs and movement systems on a mech.

Mechs surprisingly share many of similarities with tanks. One of the major similarities is that both would have their movement systems easily compromised.


Power armor is a bit impractical. It is basically an electronic, mechanized suit that a soldier wears for protection. Although the soldier's ability to move forward would be greater than that of a mecha (possibly?), it would still be affected by small arms fire. Whilst the shots would not penetrate the armor, it would most definitely throw the wearer back, much like how modern Kevlar is. If the user is less affected by the impact, and lets say only caused pain and set lightly off balance, the benefit gained from this may not be worth the mobility granted by less armor. The metal is still directly attached to the user, and his feet are still what is supporting the power armor. And that is looking past power issues, assuming that by this time energy problems have not already been eliminated.

Now, lets us once again look toward indoor mecha.

I base my theories on this video of existing technology (for theories and educated guesses are all we have right now).
If this mecha were to be more highly armored, it could potentially completely resist small arms fire. The body is supported by mechanical legs that the user operated, rather than being supported by the user's own biological legs. This could decrease the off balancing factor to zero. A mecha of this size may not be able to carry significantly larger ammunition than small arms, but would be able to carry slug (such as those seen in guns designed to hunt elephants) and fire them semi-automatically. This would be devastating during in doors combat.

The performance of a mecha like this in urban combat is not as effective. Whilst the armor would be heavy enough to resist small arms fire (much like a tank) it would be much more vulnerable to weapons that are capable in urban combat, such as the RPG or an existing tank. These weapons would be unavailable during indoors combat, thus making the mecha much more threatening. The mecha would basically serve as an indoor tank. This would be an important revelation (perhaps too strong a word?) seeing that the indoor heavy armored vehicle does not yet exist.

What I do agree on you with is that the pilots of these mechs would have to be skinny. In order to maximize the effectiveness of the mech, the cockpit would have to be as small as possible. This opens a new line of discussion: would the future pilots of mecha be primarily female pilots, due to their ideal body proportions for small cockpits?
 
     
 
Camo suits that literally make the wearer invisible by scattering/bending light would be better for urban combat. It would certainly be unsettling to see a commando squad run towards you, then suddenly disappear. You'd also have to consider that a person would have a slight speed/agility advantage; they could just ambush the mech suit from behind.
Also note that the machine in that video is suspended by a wire the entire time.

If you bend the light around the mech the pilot can't see anything.

I the post that I posted my video link into, I stated that we were thinking under the assumption that by the time we made mecha advanced enough for such combat, power issues would have been resolved. If we are referring to power supplies, all mecha are extremely useless and the idea should be aborted all together.

You're not hiding the mech. I'm saying that "cloaking" tech is a better solution than mechs to urban combat.
 
     
 
Whatever happened to all that metamaterial buzz?
     
CUDA!

On Power Armour: It is extremely practical. For one, the US has developed body armour that can stop bullets from AK47s, and power armour allows the user to carry heavier loads, armour (!) and possibly use heavier weapons without a drastic increase in size. On the power supply: They will fix that issue and I'm sure that they will fix it long before the first practical combat mech comes out. It is far more practical than an mecha built for indoors combat.

On indoor mecha: They will be too large and too clumsy/slow for the tight confines of indoors combat. If they were any bit successful, they would be forced out of their role by using IEDs indoors, which reduces the cost effectiveness of using a mech for indoors combat. Also don't assume that soldiers won't use explosives indoors, as they can and will if the need arises.

On weapons: Indoors combat does not need the use of heavy weapons. Bringing in munitions larger than what is needed for the job is impractical, ineffective and costly. You do not need large bullets to kill people, what you need are effective bullets. Larger bullets (.50 and up) are generally reserved for suppression, vehicles and buildings because they do damage to and through those objects. Likewise, if used indoors may, larger bullets may go through intended targets/obstacles and hit things that the shooter does not want to hit (hostages, allies). Slugs (shotgun slugs) are primarily used to bust doors (by breaking hinges).

EDIT: Quote tag screwed up, fixed by cutting out quotes of previous posts.
 
     
 
It all depends on what you see a mecha as. For the most part as seen in a lot of anime it is not very practical. Scientists are working on those carbon nanotube exosuits and cyborgs at the moment. Ghost in the Shell seems to be on an accurate timeline as I expect to see cyborgs by 2025.

A bullet doesn't trow you back. If this was the case you couldn't fire a rifle while standing.

Well, if you're hiding the soldier by bending the light around him he can't see s**t.

I like to define mecha as a vehicle that needs to be driven (and not worn) that relies on limbs for movement, utility or combat purposes.

Tachikoma in GitS are considered mechs with AI.

How did I miss this post?

Several tanks are powered by engines used in planes (the M1 Abrams uses a jet engine, several WWII tanks for the Allies used Rolls Royce engines used in fighter aircraft of the time). Which means that you can put a tank engine into a mech and have no problem. Power issues are a non-issue with mechs, as they'll just be using what the tanks are using. By the time mechs come out tanks are more than likely to be fueled with hydrogen fuel cells or small-scale nuclear power plants (aside from whatever remaining fossil-fuels we have).

i'd like to point out that most types if ICE's don't fare well when placed under situations where the engine is placed upside down leaving a very big vulnerability in a system that can be upended with lifting the entire vehicle.

as space elevator material principles get closer to reality, a mecha will become more practical.

The materials have to be super light and super strong - orders of magnitude better than stainless steel. Otherwise the workload on the servos is too much.
 
     
 
In the end, mechs are horribly impractical. Stuff like VTOLs, hover tanks, drones and cloaking devices are really the next step.
Afterall, you can't trip a hover tank.

hover tanks require "hovering" and in order to be statistically more terrain efficient than a mecha, they would have to have a motor with similar capacity to large jet engines, or AC-gravity, which thus far struggles to lift a bowling ball.
