The base stats of a soldier, excluding any class bonuses is 2-4 for each of the 3 perk types.
3 possible results for 3 perks.
If you desire a max roll of 4-4-4, and the probability of each stat being the same, the probability of getting a max roll soldier is 3x3x3, or:
1 in 27

But you might ask- Well, you can technically sell soldiers you don’t like for roughly 90% of the purchase price, can’t you?
You don’t even need to level the soldier up to hit that threshold, right?
Assuming you desire 10 max-rolled III soldiers priced at 9k each, you would need at the barest minimum, 90k coins.
9,000 x 10 = 90,000
But then we encounter the RNG portion of perk rerolling. The average of 1 in every 27 soldiers tidbit from earlier. Assuming we exclusively stick to that average amount and nothing else, you only need a cool 2.43M coins.
90,000 x 27 = 2,430,000
Assuming you do sell them when RNG wasn’t in your favor, you’ll get a rebate of 2.20M, and you’d have lost 229,500 coins.
81,500 x 27 = 2,200,500
2,430,000 - 2,200,500 = 229,500
Then we combine the minimum cost with the losses calculated from the sell price and the RNG.
229,500 + 90,00 = 319,500
This sets the minimum price of getting 10 max roll soldiers of 90k, and the average cost factoring in RNG at 319.5k.
This is excluding sitting on your butt and buying and selling soldiers, which costs time on your part. To summarize:
Attempting to max roll soldiers have the average cost of roughly 3 times the bare minimum cost after factoring in RNG.
These are literally the hidden costs of attempting to max roll the soldiers in your army. And this is only for 10 III soldiers, which is, quite frankly, only about half or less of the soldiers in a player’s roster for 1 particular nation or lineup.
To put it bluntly, these are a bigger money sink than weapon upgrades are. Purchasing 10 of the 3-star base rarity guns would cost a mere 130k.
(3,000 + 9,920) x 10 = 129,920
TL;DR
Remove the RNG factor of soldiers as these are not only excessively cost-prohibitive, but mind-numbingly tedious to organize as well. ~300k for just 10 III soldiers is stupid. Let alone more.
