I appreciate all the great input! One thing that seems to be a recurring theme is comm jamming. With the advancment of spread spectrum technology and reverse error correction algorithems, this will be a much smaller issue in the FAR future of Traveller. IMHO, anyway.
It isn't jamming or interception as such. If your enemy has a detector network connected to multiple near orbit ortillery relays any signal sent is asking for your squad to be annihalated. Disposable cutouts get expensive. Lightspeed return fire especially when it hits an area 20m in radius becomes hard to avoid.
Veltyn - nice variants! But where's the flamethrower version?
Funny you should mention that. I've been thinking of ways to model chemical projectors under T20 lately. Acids, thermal agents and toxins all have their place, currently there is only the plasma/fusion projectors, and they don't appear designed for wide dispersal.
Oh yeah: Heads-up Displays, too (HUDs) - it seems like these would have all kind of variation, too: basically different software packages...
A fairly good rundown of weapon enhancement HUDS are described in TA1. As a bonus they have very simple rules - a direct modification to attack bonus.
My one suggestion about your battledress: You must keep the design to 250vl or less.
Um. Regular standard design BD is 300vl. This is 3 times the size of a large human (or double someone my size). I always considered the size restriction to be based on the primary requirement of BD, being vehicle class armor that was able to move through human sized interior spaces (buildings, starships). In objective terms this means
150 VL
Some crawlspaces are inaccessible. Occasionally knocking higher extremities on door jams and light fittings. Slower movement through chokepoints. Some standard interface consoles inaccessible (thinking driving a car), though larger ones might still be useable. Marine in combat armor carrying a full kit sized.
200 VL
Enclosed spaces (cupboards for example) and crawlspaces become somewhat inaccesible. Use of 100VL crew stations becomes limited or impossible. Extensive manevearing to get though smaller doors. Larger egresses still not a problem, nor are standard corridor spaces. Robocop sized.
300 VL
Small corridors become a problem (Library stacks for example). Multiperson corridors (ie 2 wide) are still fine, but egresses designed for one person at a time become difficult to navigate if at all possible. Small doors and accessways become out of the question.
500 VL
About the limit for sharing human classed interior space. Defeated by doorways, rooves are all far too low. Wide corridors are still accessible, as are foyers, plazas and small alleyways, making this size battledress advantageous over some other vehicles. Blase destruction of low hanging objects with the nessicity of widening civilian doorways for access. Aliens Cargo-Loader sized.
700 VL
ED209 sized.
