Some can and do pursue advanced degrees, but of the handful of generals I've met, most don't. The most interesting exception was a brig who spent his entire career in SOCOM, most of which was literally on the ground with troops, weapon-in-hand. Of course his PhD and 4 post-docs were in Military Science and Military History. He got fired from Amazon for calling an SVP a cunt for not wanting to be seen working alongside wage employees. He went on to start a security contracting firm, which probably was a better fit for him anyway.
