>>489363>up to date for a weekThat's a pretty long op for standard forces, but kind of playing off what
>>489388 described, pretty much you just carry the same stuff as any other multiday work, the exception being food and water, which you will need resupply or relief in a timely manner.
>Do I understand correctly when I say they build two posts, one for relief and recuperation and one for observation, some distance away from each other?You have the idea. Basically when you're establishing a foothold in an enemy nation, as far as base structure is concerned, is to start off with central large bases, most often in locations where there is an airport or in an area where an airport can be constructed. Well that's great, but now you want to keep the enemy off your logistical supply gate, so you push out forward operating bases, or FOBs, which are smaller, more combat oriented locations that conduct patrols, the idea being if the enemy strikes into your claimed territory, they encounter pure fighting force that is an acceptable loss. Even if the base is overran, you have time to manuever more units into the area, or depending on the strength of the assault, time to decide if it's time to pull back other FOB assets to the main base, so on so forth there's a billion tactics you can use depending on your opposition.
Now, observation posts do similar to a FOB, but on a smaller scale, aside from launching patrols to discover threats that might be creeping around, observation posts are set up forward of the FOB, to alert the base of any and all activity, get a feel for how the locals act, and most importantly report any changes. If there's 50 cars going back and forth on some road throughout the day, every day, and suddenly no cars are on the road for the entire day, there's a possibility something is up and the locals know about it. Could be an IED, could be a planned attack, could be nothing, but changes are red flags.
