We have several hundred M113s in inventory, many of them he A3 variant.
The M113 was a true “battle taxi”.
Light (relatively), maneuverable and no-frills.
I spent a good chunk of my career in th M577 variant.
Relatively reliable and simple.
When the Stryker was first fielded, the size and cost drove many to long for their return. However, the simple aluminum “armor” would have been disastrous. Marine AAVs of similar construction have been literally peeled apart from IEDs, taking the entire compliment with them.
Back in 1985, I had long, heated debates with fellow soldiers about the need for the Bradley. I’m glad to see that it’s proven to be very effective and reliable on the battlefield (as I knew it would be). Bradley’s have been called into action to support Marine operations (Fallujah) when the LAV was proved inferior.
