Asharohi Soldier on a horse
Gaja Soldier on a elephant
Arhda rathi A experienced warrior skilled in weapons
Rathi A famous warrior Expert in weapon skills
Atirathi A master of weapon skills

The above ranks are not just a reflection of skill or mastery of a weapon. It also includes knowledge of battle formations, strategic skill set, tactical knowledge, past experience, ability to crack "battle traps" and so on. Simply because an archer rode a chariot did not make him a Rathi – the warrior needed to have some fearsome reputation and class battle experience too.
Please also note that just because a warrior has a higher rank, that doesn't mean a warrior from a lower rank cannot beat or kill him. Example – Shikhandi was only a Rathi but he ended up killing Bheesma – a Maharathi.
