Double, but this was a pretty good one.
The seaport at Kavala had long been a problem for operations in the area around Kavala. It had a large garrison, 2-3 squads, and plenty of sight range around the port and across the bay. It had only one main entrance, well covered by the enemy. The worst was the attack boat parked at the seaport, which would shred any frontal assault(first-hand experience) from a position where itself was protected from attack.
A two-part assault, one part consisting of me, an autorifleman, and a medic, all in a machine gun-equipped truck, and the other a mortar team at an outpost about 1.5km away. First phase of the attack was to park the truck just a bit from the south side of the bay(seaport was the north side), and called in several mortar strikes on enemy positions spotted with my binoculars. Then I took out my MAAWS AT launcher and put a 75mm HEAT rocket into the side of that attack boat(a 300m-400m shot). A random street patrol nearly screwed the mission, wounding both my team members, but it wasn't serious damage. I call in some more mortar strikes for good measure since I saw some more enemy troops standing and some more on my map.
Getting to the seaport, I had no resistance. Nothing but bodies, dozens of them. The mortars cleaned the place out. I can only surmise that the enemies marked on my map were wounded, only to be finished off by direct mortar hits. There was one random rifleman who popped his head up only for it to be blown off by the truck's .50cal. Apparently the display was enough for Kavala to change its allegiance to my faction. The only other enemy stronghold left in the city is Kavala Kastro(castle).
While I was looting the base's ammo crate(rebreathers and scuba gear, neat), I hear an enemy helicopter flying in. It's a transport, carrying a full force to counterattack. I fire a rocket into it and the truck's gunner shoots a few bullets at it, forcing it to the ground. I had expected the rocket to destroy it, but that's fine. About half the troops on the helicopter surrendered immediately, while the pilots and the rest of them tried to fight and were immediately put down. Since the helicopter was now empty and only disabled, I tried using the commander menu to send it to the faction garage.
It worked. The resistance now owns an armored transport helicopter.In short, we took over Kavala, one of the largest cities in Altis, secured the vital seaport, captured a helicopter, took almost a dozen prisoners(they were released, which I think gives you HR points), and took NO losses. And did this with only 5 men - two of whom were the support unit and one of whom was me.
