1. Ammo going down, more than likely not, people are still buying it now, at a pretty rapid pace I believe, so they will probably not lower the price it may stabilize, but not go down.
2. We can't have a large buildup of troops in Afghanistan. If you want to know why from someone who was actually there, continue reading if not skip the rest of this message.
Look at a globe, or a map, Afghanistan is a land-locked country, there are no ports. So what we have planes right? Well we have to get permission to fly over a couple of countries, ok that’s not that big of a problem, but every soldier/sailor/airman and marine uses a certain amount of supplies a day lets say 12 pounds, water food, fuel etc... If it cant be flown in it has to be trucked in through Pakistan...that’s a whole thread in itself. The max number of troops that can be supported in Afghanistan for a sustained period is around 16,000 plus the 3-5,000 private contractors that are there. The Russians found this out the hard way, logistically it is impossible to fly that many fights to sustain even half the number of military personnel in Iraq in Afghanistan, Iraq has ports and we have trucks that distribute supplies all over Iraq. But hey I could be wrong they may just have round the clock flights and air drops to sustain 85,000 troops in Afghanistan.
