As someone pointed out, "What's to stop a clever infantryman from
chopping the cable."  Same thing that has the Angles attacking the
EVAs instead of their cables.  Stupid plot devices.  In effect, the
most efficient attack that an Angle could have performed would be to
snap the cables until the EVAs ran out of them.  Simple.

That was me. I think it would be practical for infantry and not angels
for several resons. An angel is an obvious target, which you can see
coming. Infantry are small and can hide themselves pretty easily,
especially considering WW2 tank sensors consisted of 'looking out the
window'.

Agreed.  Sheathe the cable with armor?  I guess thats impractical.

Also, angels only ever attacked in ones or twos. A single EVA, or a
squad, could easily watch that many targets and block any attempts to
reach the cables. Conversely, 20 infantrymen coming from different
directions would provide too many targets. At least one of them would be
able to get close enough to get through. That is teh reason why tanks
were vulnerable to infantry in urban warfare. There were too many hiding
places for infantry to get close and dump a grenade through a weak spot.
This same vulnerability that tanks had to infantry would be present in a
WW2 mecha.

I agree with your assesment on the infantry, but I still think it
would've been damn easy for the angels to go for the power supplies.
As I recall, a moving angel isn't the easiest target.

Finally, I *think* the angels were 'agents of divine retribution' (not
literally). What I mean is they were 'programmed' to act in a certain
way, which may havce included a defination of 'honourable combat'. That
would certainbly stop them doing the dirty on the power cables. WW2
nations were under no such restrictions of honour codes. It can be said
that even Japan manipulated its martial honour code to get its soldiers
to do otherwise suicidal acts of heroism/stupidity. USA used nukes,
which we now considerable a dishonourable weapon in *future* wars.
Britain considered using Anthrax as a weapon (check out that island in
Scotland). And Germany would be the last nation anyone would consider
'honourable'.

Uhh... Honorable combat?  I didn't know mental rape was under the 
heading of honorable combat...  As for your assessment of the German
military, you're being biased.  The German Military mostly came out
of a proud and honorable tradition.  It was the SS that did most of
the butchering.  Also, the code they followed demanded absolute 
obediance, which is one of the reasons they lost the war (If his
generals had run the war, Hitler may have won...)  The Nuremberg
rulings, though they extracted proper revenge, were hardly just.
They broke with all tradition when they indemnified somebody for
following orders.

WW2 mecha would fight best in open countryside, ideally fighting
equivalent sized opponents (ie tanks or mecha). They could mow down
infantry in open country until the infantry got too close to the cables.
In a city they are just a funny shaped tank with a power cable as an
extra weak spot. Mecha could also make decent AA platforms.

I posted already about why I don't think they'd be able to fight in 
open arenas, especially since I doubt they could match Tanks in 
speed or fire power...  I also disagree about AA platforms.  The
"autocannon" point defense idea is a recent invention.  The old AA
guns consisted of 78 (?) mm guns which shot huge shells into the
sky.  As someone pointed out, you can't load something like that
onto this "walker"

The biomechs someone mentioned appear to be the best means for getting
around real-world physics. They need no power cables, and onboard fuel
isnt a limiting factor. Make the biomech muscles have some regenerative
powers, else a flamethrower would play havoc. You could even have flying
mechs with wings :)

Mmm... Now we're sounding like Battletech.  As for flying mechs, that
isn't going to work.  You'd need a hellish amount of lift to get something
that heavy in the air...  The key problem with regeneration is: Where
the hell is the matter coming from?  Unless you've got one of those 
nifty Startrek Energy to Matter thingamajigs...
