Tier 3 Basics are currently one of the rarer Rank Up materials in the game. There are definitely ways to get them, but they're not a very quick and easy item to gain. This won't always be the case. Over time, you'll be able to get them more often and easier, but this is still a little ways away.
In the mean time, these guys have given you the correct places to get them. Alliance Missions are the main source for them (and will continue to be the place to get Rank Up materials consistently in the future), as well as the new Monthly Spotlight Missions.
There will be more ways in the future as well, so keep an eye out for those!

Spotlight events like current one give t3 in hard as well
