Ken Pick added a whole bunch of possible extra small arms and support weapons
for Striker in Challenge #64, #65 and #66. They are available here:

I'm confused by the interaction between the tac missile propellant design
sequence table errata you have posted Don, and the 2ed Striker table
explanation, which already says to "add 1 if TL6" implying to me that they are
TL7+ already.

The errata on agility calculation is fine, as far as it goes, but it does not
solve the conundrum of calculating a spacecraft's agility in Striker terms (as
we've discussed here in the past). The problem is that the Striker agility
calculation formula on page 27 requires things such as percentage of weight
devoted to man. enhancement - which we simply do not have for a Book 2/HG2ed
spacecraft - and man. points derived from the type of controls fitted.
It is also unclear why we check the HG agility against the max. speed table
rather than the Man. Gs of the spacecraft.
