Commendations help - AEON and Blindside

I’m currently trying to get the Blindside visor and the Orbital AEON set
In the way of getting Blindside, im on Avenger - Master with 24/360

For Orbital, i need to complete Covenant destroyer, where I have
Elite General Slayer - Mastered
Elite Zealot Slayer - Master with 114/300
Grunt Imperial Slayer - Master with 18/900
Jackal Ranger Slayer - Mastered
Elite Officer Slayer - Mastered
Grunt Ultra Slayer - Master with 273/350
Hunter Slayer - Master with 2/250
Jackal Major Slayer - Master with 49/500

The reason I’m posting this is to ask for help on how to get these comendations in a faster/easier way. Especially for Covenant Destroyer.

I just got AEON and Blindside not too long ago. For Covenenat Destroyer,theres a chart you can google to find what missions have the most of certain enemies, like for hunters, You can keep playing the Mantis mission on Ragnarok because there a bunch of hunters that get dropped. Elite Zealots are plentiful in the final mission, and many missions on that same map. What i did was just play through SpOps campaign again and again, like 3 times over a few weeks and got the AEON with ease. Hope this helps man

This should help you.
