This is really a limitation of the skill tables from Classic Traveller. MegaTraveller and T4 got around the problem via Cascades, but the problem is bigger than just Scouts and Survival..
For example, the following skills are unavailable to Army career characters in the first playtest draft: Advocate, Animals, Art, Astrogator, Battle Dress, Broker, Carouse, Deception, Diplomat, Engineer, Investigate, Jack of All Trades, Language, Navigator, Persuade, Pilot, Recon, Science, Seafarer, Steward, Streetwise, Survival, Trade, Vacc Suit, and Zero-G.
Most of that is ignorable; however, I'd think that at least Recon should be on the Army list.
Navy is interesting for lacking Leader, Medic and Tactics; this should make fleet combats quite interesting.
Marines lack Admin, Gunner, and Recon. Maybe they use Army and Navy administrators.
The Scouts are missing several interesting skills, like Admin or Carouse, Gunner or Investigate, Language, Melee or Survival.
The point is that at the moment we've got 44 skills, of which Agents have access to 15, Navy and Entertainers 16, Scholars and Drifters 17, Nobility 18, Army and Scouts 19, Marines and Merchants 20, and Rogues 22.
The problem is that the Tables as created are really copies of the CT career tables, but there are quite a few more skills than in CT. The problem gets worse when you start looking at skill specialties and career specialties.
So I'd like to suggest that perhaps the real work is in the skill tables for the careers.
