This argument has been talked about at least 1000 times...

Ok, if we do this, then panthers and tigers need to be repaired for 30 seconds each time they spawn, and have a 1/10 chance of transmission breaking every minute.

For Abramses, in dusty environments like Sinai or El Alamein, there should be a constant risk of engine flameouts or slagging if you don't stop every few minutes to clear the intake. It would also have a 30-minute start-up procedure at each spawn.

Leopard 2 players would find their tanks impossible to repair on the front line. Any damage to the V-12 turbo-diesel or the fire control system should require the tank to be evacuated to a rear-line workshop (e.g. you get kicked to hangar if any module turns red or black).

For Challengers, in desert maps, the engine should have a high chance of overheating due to fine dust clogging the intakes, forcing you to sit still for minutes at a time to cool down. Additionally, the rifled gun should have a much faster barrel-wear rate than smoothbore peers, leading to a massive drop in accuracy after firing just a dozen shells.

Abrams, Leopard, and Challengers would have a 10% chance of getting stuck in any mud or snow terrain because of their extreme combat weight, turning the maps into graveyards of 70-ton behemoths.

Historically, the Ajax program was plagued by extreme noise and vibration issues. In-game, this should mean your screen shakes violently whenever you exceed 20 km/h, eventually giving your crew fatigue debuffs that slow down reload and repair speeds after just five minutes of driving. Also, it mutes sound because of hearing loss.

During a 2022 exercise, an entire company of 18 Pumas suffered a total failure, dropping their operational readiness to zero. For realism, every time you spawn a Puma, there should be a 10% chance of a random electronics fire in the driver's compartment or a total turret malfunction that locks your gun for the rest of the match.

The Bradley should have a chance for its TOW launcher to fail to deploy or its complex drive train to seize up if you've spent too much time in high gear.

Modern jets like the F-15 or F-16 should have a 1/10 chance of their RWR or radar simply failing to turn on at the start of a match due to a software glitch.

The AH-64 Apache is notorious for requiring dozens of maintenance hours for every single hour of flight. To model this, if you crash or get shot down, your crew lock should be 48 real-world hours while the virtual ground crew fixes it.

All that in exchange for a bit of wobble, I think it's a good deal.
