Note: this mod stop at version 1.3b. Version 1.4b concentrate on expanding Chinese Remnant force so I arrange for a separate page, but still keep same filename. Players only want Enclave can play this one, want Enclave + Chinese can play the other. Same Enclave content on both versions.
--|--
What did the Enclave do before their full invasion happen? The airdrop over at Project Purity is a little too sudden. Almost no sign of recon, no forward base and BAM! Troopers dropping out of nowhere with mindcontrolled Deathclaws in tow. This mod attempt to provide a little bit of forboding foreshadow for that.

The central of operation is the hidden Enclave Clinic complex in the north. From here, a team move out to secure Old Olney as base for future ops in the northeast. A recon team park outside of slavers central to keep an eye on this possible trouble. Another team build up a semi-base in Collapsed Tunnel, overlooking the river, the major landmark.

Operating further out is one recon hide near the vault 87, the source of hostility in the entire region. One team get surprised by SM in Project Purity thus entrapped in the listening post riverside. Thus they cant connect with the special force hid in a White House West Wing bunker ready for secure LZ. And one team parked in Springvale, prepare for troubles from Megaton when vertibirds fly over their heads.

I am open to suggestion for some logical places. This mod has Enclave Recons as central theme, so places should be where that is applicable~

*Location* 
[NEW v1.3b addition] A complete 3-cell preWar facility was captured and reconfig into a clinic for Enclave recon teams in the northern lands. This safe base also contain an armory full of ammo and weapons for resupply.
Olney safe house is nested inside a ruined building just south of the mapmarker Ol Olney .
Collapsed Tunnel house a ruined shack on the outside, a long room on the inside as safe house for mobile infantry in the coming invasion.
The Enclave's Bunker is in a nook in The White House's West Door, house a special team preparing for coming sudden strike to secure landing zone for verti-drops.
A recon team comprised of Suspicious Man/Woman stay outside of Paradise Falls.
A recon team in Silver's ranch near Megaton 
A recon team surrounded by Super Mutants was blocked inside a hidden bunker near the Jefferson memorial souvenir shop. Look for the big rock.
A tunnel hide sufficiently hidden southeast of V87, northeast of Lamplight to keep a close look at the source of hostility in this region.

*NPC and creatures*
Special bosses using standard face of Stella, Arcade, Christine,Veronica...
The recon fake friendly to stay close, keep quiet, until the enclave get attacked.
The open hostile are robots, mostly Overwatch Protectron. When they detect your presence, the Suspicious Man/Woman no longer stay friendly.
The rare Enclave Cyberdogs are in the central base only, because if they ever poke their heads out for scav to see they will be captured for sale to the highest bidding~

*Weapon/Armor*
"32 SMG, Enclave modded" just because.
20 gauge Pistol Shotgun for the crazy shotgunfags... which I am one.
Place a few specific vanilla unique weapons and armors, Thor, Paladin Toaster, Pushy. Some more in Enclave Clinic's Armory.

*Loading screen*
All the location have mod-specific loading screen tips.

This mod is a very lightweight building and location. The NPC are modified from certain popular characters like Arcade, Stella, Vera etc... Interior is taken from vanilla data. At first I was thinking about reuse the Remnant bunker in FNV but it's not entirely fit, so... The White house bunker get reduce to a small bunker for a reinforced squad (10), staying outside of West Door. The other safehouses are basically wasteland rooms after cleaned up. The central base is a preWar clinic get repurposed first to a research base, then later on to a hospital and resupply base for northern recon.
