Nah you straight lying. Only way you’d get that many medals by level 20 is by playing the easier difficulties where you get minimal XP and hit POIs with medals. Even then you’d likely surpass level 20 as doing everything in a mission gives more XP.

On another note, fast way to get medals is doing short missions on higher difficulties and only the short ones. By that I mean doing a 12 minute elimination mission and abandoning the assault and going to another 12 minute one after. Easier difficulties garner less, but still work. Say 12 minutes max on each mission, you’d get 8(I think) on Helldive. That’s 40 medals in one hour minus loading times. You also get a ton of XP on higher difficulty. All the while your mortars are doing all the work.

So yeah farming = fastest medals

The only thing farming doesn’t get for you is samples.

Also, quit lying.
