Started going to AFG in 2002. Was last there in 2018.
I visited most, if not all, C-130 capable airfields in the country. In addition to the most important/worst part, the human cost, we watched the bases go from old Soviet buildings, to tents, to B-huts, to shipping containers, to hard billets, and then abandoned. Buckets to port-a-pots, to cadillacs, to proper shitters, then abandoned. The continuous pouring of square miles of concrete at every airfield. Giant bases created in the open desert and then bulldozed. The contractors everywhere. We looked down on the continuous train of supply trucks stretching halfway across the country from Pakistan. Watched the 24/7 arrival of equipment, MRAPs, M-ATVs, earthmovers, construction equipment, trucks for years on end. All used up and now rotting in giant graveyards.
Trillions of dollars disposed of in that wasteland. No point, just don't know what to think of it all.
