One big thing to remember in Traveller is that with multiple-specialization skills (like Gun Combat (Slug Pistol) 1) it still means you have 'Gun Combat 0' in everything else. Which means you DON'T have the -3. So as far as Engineering goes, anyone with Engineering 1 in any particular thing can still do other types of engineering just fine. You just have the advantage of better bonuses in your various specializations.<br/><br/>(BTW, I don't know if this got caught or not, but I vaguely remember last week or so at some point seeing an 'Energy Weapons' specialization in some character sheet or other. It really should be Energy Pistol/Rifle/Carbine. You have to focus your specialization a bit more than that. :)  )
