The fact that Aisha couldn't extract information from them was quite noteworthy, don't forget that she has a few hundreds of years of battle experience and unlike currently, there was a war in the open between forces of the four galaxies when she was in her academic years, something that ended at Aliyah's generation.
And as one of the main representatives of her generation from the Immortal galaxy, she of course was a priority target and thus dealt with a lot of enemies back then, what's more unlike Liz or Elaine who at least had Erin as their backing in the Revy family meaning they had a trustable team accompanying them when they went out in a mission, the Silverheart treated Aisha more like a tool than a family member, so she preferred to ditch the guys that were only there to keep and eye on her and do all the roles in a team by herself.
So, scouting, fighting, intel gathering, strategy, she had experience in all fields, though her specialty was battle of course.
