[VVerse] Warp point assaults/Fixed vs Mobile Defenses

The problem with fixed defenses is that (assuming attacker's knowledge 
of the defenses.) the attacker has more time to solve the problem of 
attacking..
The defender has a fixed amount of time to design his defenses (because 
he has to build them), but the attacker can plan until he comes up with 
a solution (and possibly even change his force structure...  And once 
the defender has invested X amount of resources in the fixed defenses, 
he can not easily reallocate them to other tasks
Mobile defenses increases the number of problems the attacker has to 
solve ( possible permuations), and makes recon much harder,

I think back to the Bar Lev line in 73 Arab/Isreali war..  The line was 
never intended to stop the Egyptians, just that it was supposed to slow 
them down enough (48 hours) to let Isrealis reinforce.. But because the 
attacker's knew the what the defenses were (huge sand berms), they could

PLAN and solve the problem (which was using water houses...)

Most SF downplay fixed defenses due to ballistic missile/Knetic 
attacks.. It is normal (in the SF arena) that most weapons have far 
longer ranges than fire control range..  ie ships/tanks etc engagement 
range is based on fire-control range not on the absolute range of the 
weapon, but a fixed ( non-manuvering) target makes the fire control 
problem much easier (ie allowing for longer ranged fire) (ie I KNOW 
where you will be in 1 hour, I do not have to use "smart/targeted" 
weapons) ..
