Had an epiphany today.
Tuned into a stream of a top team and watched the streamer playing Armoured/SOF in a tight urban area and get absolutely rolled off his point a Guard/Mot player with a combination of BTR-82s and T-15s.

Basically the BTRs would roll in first and all die to the RRC and MAAWs teams he had lurking around, then the T-15s would roll in and all the AT infantry was already at half health or out of ammo so they just got bowled over.

I realized something watching this: durability matters. Small squads kind of just lose half their health to a shitter vehicle before they can kill it, and since you only get a small number of these premo tank hunter squads you can't afford to let them exhaust themselves killing easy targets as long as a tank might roll in afterwards. Obvious RRC and MAAWS are extremely good, but since they're expensive 6 man squads, it would be beneficial if they had something else with them that could soak damage, or deal with the low-armour vehicles that don't really require a triple-carl G to hurt so they can preserve their strength for the targets that matter.

So I did what any good autist would do: I made a spreadsheet. A simple one. Basically, just how much a squad costs vs how many models you get in the squad, and the ratio between them represented as "PPM" or Points per Meat. A lower number is better, because it means you spend less for more meat, and you can use meat squads to soak damage for valuable squads, eat up APS charges or counter low-value vehicles like BMPs and BTRs to preserve the strength of your more valuable units.

For completion's sake I listed armour values as well, though I don't know how much they really matter here. I also colour coded for readability:
Best PPM in faction - green
Notably good PPM - blue
Terrible PPM, avoid putting in harm's way - red

Obviously there are mitigating factors involved in cost but this gives a better idea of the relationship between cost a survivability.
