What sorts of advantages and upgrades will characters gain access to as they grow?

It is really long and complicated to go deep into the character's growth system, so I will try and explain the basic concepts. There are two growth paths. The character growth is positively related to two factors - the play time and the record, such as team record, obtained credits, number of player kills and death. The record factor differentiates Huxley from other MMO's growth systems. The two factors influence the character growth independently. The growth through play time can be again separated into vertical and horizontal growth. Horizontal growth means acquisition of additional skills for more advanced and diversified game plays. Vertical growth means increasing strength or power. Finally, a character's record dictates its growth in standing. With a better record, you can climb up the hierarchy in the chain of command for more authority in battle.

The key objective of character growth is to increase the ability to handle a variety of situations. In a massive battle, you face many different challenging situations. You might have to defend the Headquarters by yourself or urgently transport troops by vehicle, and so on. As a character grows up through many hours of play time, he or she will be better fit to handle those situations.
