Yes, that's the average time since a depot-level overhaul (Anniston Depot in conjunction with the General Dynamics Army Tank Plant in Lima). They restart the vehicle's life cycle clock after reset..
This is interesting, as I can only assume that not every piece of the tank is refurbished or replaced during each depot-level overhaul. Guess that's why they use the term "Built like a tank!"
It's hard to see any reason to gripe about the Army spending money on uniforms. We have the worlds best tank and therefore the Army isn't asking for better. If only our sister services had any such concept of restraint.
By Title X, the folks here in the Puzzle Palace are required to support the troops in the field, providing oversight towards supporting, equipping, and training them to be able to provide for the National Defense.
Towards the "equip" side, despite common misconceptions on "wastefullness of the process", it really becomes finding the right balance to ensure we can replace equipment either worn out or no longer assurred of achieving mission success. That latter part is greatly influenced on the ENEMIES' capabilities, and usually not ours.
We have the best tanks in the world now, and that should remaina fact for a while. This is quickly becoming "not the case" in regards to air power and sea power. There are several potential opponents who are quickly catching up, and potentially exceeding, our ability to project air and sea power. This is why the services are now calling for better and more advanced aircraft, and better sea power projection capes.
Granted, it seems that constraint needs to also become a catch word here in the building. I think our current economic pressures, and the push to mostly solve it through defense cuts, will force ALL the services to increase that restraint.
And yeah, that includes not going out and replacing perfectly good uniforms just for the sake of replacing them.
