In my personal experience, I targeted the loyalty missions, architects of each world and just general main story progression and this popped up in no time.
This can also easily be done in Multiplayer, however if you prefer the Singleplayer approach, you won't be disheartened.

If you are dilligent in completing as many Secondary Ops and Additional Tasks as you can in the game, you should be able to hit Level 40 in one playthrough (this is not the level cap, by the way - you'll probably be able to get well over that). It will help to equip any armor with +xp bonuses to get this more quickly (which will also help you level and be stronger if you're going for Unwavering on Insanity). If you pre-ordered, the armor you get from that is worth a 35% bonus. If you do not get this during your first campaign, you can start a NG+ and continue to work toward it. Here is a great way to farm xp if you need to.
Otherwise, you will need to play quite a few matches in MP to get a character to Level 20. You will want to focus on a single character (which can be annoying since you'll unlock cooler characters as you play), but it will simply take time. You get experience bonuses based on kills and medals, so try to play well and not just be carried along or it will take longer.

This trophy can be done in single player or multiplayer.
In Single Player:
You need to reach level 40. This is easily achieved way before you complete all other single player trophies. You earn experience for killing enemies during missions, and completing missions.
If for some instance you have all other single player trophies and still need to get to level 40, then you can use the infinite experience glitch to level up really quickly. You'll be getting 6,000 - 7,000 exp/min and should be level 40 in no time. The video below shows this infinite experience glitch in detail.
Infinite Experience Glitch (6000-7000 exp/min)
In Multiplayer
You need to reach level 20. If you are going for 
Unwavering by finishing 5 Gold Extractions in multiplayer, then you should be level 20 by the time you obtain that trophy. Just keep finishing extraction missions and earn many different medals during your play to boost your experience you gain. You can also also gain experience boosters (increase earned experience during one match) that you can get randomly from supply drops.

I recommend choosing the difficulty based on your character.
Bronze. 1-9 lvl.
Silver. 10-16 lvl.
Gold. 17-20 lvl.
If you have the finances for the tasks, I highly recommend purchasing additional equipment.
Now for 120 coins, an excellent golden “Juggernaut Shield” is available, which gives +10 shield capacity and +75 damage in melee combat. Later, there will definitely be other items that are more suitable for your playing style and favorite character.
The simplest opponents are bandits.
The simplest maps are Base Zero and Base Ruins.
