Decided to move HQ to a small, unmarked farm(? no farmland around it) a little ways south-southeast of Negades. Primary reason was the only Logistics missions Petros was giving me were Steal/Destroy Ammo Truck as opposed to City Supply deliveries. And while I actually wanted the ammo-truck missions to buff up my arsenal, the only ones of those he was generating were either one that buggered CSAT or one that required a full-on amphibious assault with limited forces(ie I couldn't bring my OP tank). The area around Negades still has several AAF outposts the mission template can utilize.
I move camp without too much issue, then saved, but when I tried to add men to the HQ garrison, I get a warning about enemies too close to add to garrison. I figure this proximity range for that is actually pretty wide, since the same enemy proximity denial for fast travel is pretty large as well. I'll just get everything unpacked and I'll do a sweep of the area for any random patrols.
Literally as I decided that, gunfire erupts from a very close distance. I see at least two AAF troops firing at Petros(they prioritize him over you), about 50m from the base perimeter. I take one sidestep, and immediately take a bullet to the face - one that would have probably killed Petros if I
hadn't sidestepped. Bear in mind, the penalty for dying/respawning is
significantly less than the penalty if the enemy kills Petros.
Since Petros was still going to die, I simply Alt-F4'd right there and just start from the most recent save. Only major loss was a big pile of landmines I had an engineer clear from a minefield near Therisa. Not sure if the truck he was supposed to be storing the mines in got saved - the engineer wasn't, as AI troops are simply refunded in cost instead. And even if it was, I don't know if the cargo would be too.
EDIT: Spent at least half an hour, probably closer to an hour, defending a constant attack. Was actually going pretty well. I had lost about three dozen soldiers total out of everywhere that was being attacked, compared to the enemy losing roughly the same number in
vehicles. APCs, helicopters, jets, UAVs, even a tank, all brought down as they crashed against layers of prepared defenses. In terms of enemy manpower, consider every APC and most of the helicopters carry probably around a dozen men, not counting crews. They probably lost a couple of company-sized forces(according to
this, it'd technically be called a "troop", not company, since they're armor/airborne forces).
Then my tank was vaporized by a random airstrike. Just because.
On the plus side, I did find comments in a few places that this size of an enemy force may actually have been a bug all along.
