The Battlemaster is actually the CO's ride.
Cyclops is the XO.
Rifleman is "bodyguard" so to speak.
Stinger obviously is the scout.
The Command Lance is one of the pickiest of lances to meet the listed requirements.
The roles have to match up just right.
Battlemaster- Brawler
Cyclops- Juggernaut
Rifleman- Sniper
Stinger- scout
If you modify the Rifleman enough that it is no longer classified as a Sniper
then the entire lance no longer qualifies as a Command Lance per the AS rules.
50% of the lance must have one of the following unit roles: Sniper, Missile Boat,
Skirmisher, or Juggernaut.
I've run a Command Lance since the 80s that consists of a Marauder, Archer,
Warhammer, and Phoenix Hawk. A pretty classic lance-and it's even pictured on
page 39 of the rules that came in the new AS rule book.
When playing Classic if BV was a problem I would often replace the Pixy with a
Fire Javelin or Firestarter.
I can't do that in AS and keep it a legal Command Lance.
The catch is that my Marauder is the MAD-3D variant. The same Mad many
players choose over the 3R for a command mech. AS classifies the MAD-3D as
a BRAWLER instead of a sniper like the MAD-3R. Even though I've seen
it used that way Extremely rarely due to it's armor and in Classic the heat makes their
long range damage almost the same, that's how AS classifies it's role.
Tinkering with the Rifleman could cause the same problem for you.
What saved my lance from being forced out as a Command Lance is that
the Phoenix Hawk is a Skirmisher and it makes it meet the 50% requirement.
Now I can't downgrade it to save PV in AS though.
