General's defender retinue

[Toast]

the 'Leadership' tech allows at chapter 2 to give your general a defender retinue upon defense.

My retinue are halberdiers. How can I get these troops upgraded? What decides that they should be halberdiers? all my garrisons are fusiliers or better? same with my traps.... just wondering what I need to do to make them better?

You can't upgrade them until Global Age, where there is a library tech to upgrade them to gatling guns.

ah. ok. bit rediculous, but fair enough; at least I'm not missing something or suffer from some weird bug.
time to get the upgrade at the library then...
