How does one use Armor Mods?

If One levels up to 50, selects a specialization, then levels to 60, wouldn’t one be forced to change specializations?

Then once changed, doesn’t one not have access to the mod?

Curious?

You can access the mod , but you do not HAVE to use it. The new support abilites you get will be under “Support Abilities” in your spartan hub

Actually when your in a specialization it locks the other ones.

im currently operator and can still use my stalker"nemesis" support up grade.

I am SR-69

No support upgrades from previous specializations.

No joke, my game is broken I guess.

The upgrades can be both support or tactical
and if you beat two specializations
you can use both abilities.

You are not understanding, they are not there.

I went through Pathfinder, and no mod is there to use.
