Imagine you're in a country that tends to pinch pennies when it comes to the defense budget. Now imagine that you're looking to upgrade your armored fighting vehicles (tanks, infantry fighting vehicles, armored personnel carriers), but you've just been told you can't buy new ones — even second-hand vehicles aren't an option. Sounds like you're stuck with obsolete vehicles, right?
Not necessarily. Believe it or not, those old tanks can be given new life, and the process is actually very simple and relatively cheap. More often than not, your real problem isn't the armored fighting vehicle itself, it's what goes on top: the turret.
This is where the firepower of your typical armored fighting vehicle resides. Thankfully, the great thing about turrets is that they can be replaced quite easily if you have the proper facilities and trained maintenance personnel. If you have a perfectly good hull, swapping out the turret is a great way to buy time and extend the service life of an otherwise-outdated and outmatched system.
The baseline BTR-80 has a KPV 14.5mm machine gun, but a new turret can make this a BTR-80A with a 30mm auto-cannon.
Russia is doing just this with their BTR-80 and BTR-82 armored personnel carriers. The baseline versions had a manned turret with a KPV 14.5mm heavy machine gun. However, the Russians replaced the initial turret with one that houses a 2A72 30mm auto-cannon — similar to the 2A42 auto-cannon used on the BMP-2 infantry fighting vehicle and the Mi-28 Havoc attack helicopter — thus creating the BTR-80A and the BTR-82A. According to some reports, Russia may make another turret switch for the latter vehicle, giving the BTR-82A a 57mm gun.
During Reforger 82, when this photo was taken, the M60A1 tank was still in widespread service, even as the M1 Abrams was starting to replace it.
Tanks also benefit from this upgrade treatment. For example, Turkey was able to extend the life of 170 M60 Patton tanks by going with the Israeli Sabra upgrade, which essentially puts a Merkava III turret on the Patton's hull (a few other upgrades were made while they were at it). Egypt is also looking to do this with its fleet of M60 main battle tanks.
The centerpiece of the M60T in Turkish Army service is a new turret like that on Israeli Merkava tanks.

The fact is, if you have an older armored vehicle, just junking it or passing it on may not be the best option. You might find that the better bargain is in getting a new turret instead.
