How would you describe the difference between the Infiltrator and Scout specialities (for RECON)? They are very similar, but I can see how they MIGHT be used in different situations.
Consider this: If a PC/party approaches an encounter with another group, I would ask the PC 'keeping watch' to do a Recon (Scout) check (passive*). If one or more PCs want to sneak up on the opposing group, I would get them to do a Recon (Infiltrator) check (with the PC with the lowest Recon skill rolling) -- I am treating this situation like an ambush. In addition, these PCs could use Recon (Intelligence) to find out something about the enemy stats. This seem like a LOT of Recon rolls, which is contrary to the "Don't roll to often" suggestion (p.45 Player's Manual). What do you think of this?
Finally, there are the "Weather & Darkness" (p.160 PM) and "Ambushing" (p.143 PM) tables. When would you use these for the Recon checks above?
* A passive Recon roll, as explained in the "Keeping Watch" rules (p.143 PM)
