That sounds close enough for a video game, except maybe capturing the airport. I’m not sure if there were any airstrips in South Vietnam or whether anyone ever took them.
Here is just an “extra” knowledge dump that may contain things that may make for an interesting scenario. There may be some keywords worth googling to find out more about, or maybe not.
The Green Berets usually worked training locals, and I mean Montagnard or civilian irregulars, not South Vietnamese troops, and took them out on various missions. While an “A-Team” was made up of around a dozen Green Berets, it may be working an area with several villages and patrols were often made up of only 2-3 Green Berets and 5-6 locals, but they could mix their teams for larger missions.
I doubt you could work the Montagnards into a video game, but it would be cool if you could. These locals were natural jungle fighters who grew up in the mountains and could often track people like a bloodhound. Imagine that Native American guy named Billy in Predator, exept better.
The Vietnamese had driven the Montagnard into the mountains a thousand years before and they still had a beef over it and there was nothing they liked more than killing Vietnamese. I’ve read about some that couldn’t stop giggling through firefights because they liked it so much.
Not only were they great fighters, but these were some of the most dedicated and loyal men in the country. From one book I read, by a Green Beret CMOH receipient named Miller, he was settling the team down for the night and mentioned “an orange soda would be good right now.” The next morning, he saw one of the Montagnards walk through the treeline, past the rest of the team and up to him, then he reached in his backpack, pulled out an orange soda and handed it to him. The guy had spent all night walking like 10 miles through enemy territory at night, back to the US base, sneaked through the perimeter and back to give the guy his soda. Then 10 minutes later it was time to go on patrol for the rest of the day and he never missed a beat.
If I had a team of those guys in a video game, I’d win it in record time.
The Green Berets did a lot of work in Laos and Cambodia as part of MACV-SOG. This group could also include SEALs, but the Army seems to have been the primary supplier of people for that. A “boring” mission might be to recon the Ho Chi Mihn Trail, call in an airstrike when a convoy passed then try to get back to safety when enemy forces came looking for them. If they were lucky, maybe they’d pick up a prisoner. A hairier mission might be “Scramble! A pilot went down in Laos in this area. Go look for him.” Usually being shot down meant the enemy was near and these guys may be dropped in the middle of the enemy without maps or any kind of support. I’ve read of this happening and the weather kept them from getting out for days.
The SEALs mostly hung around waterways in the Mekong Delta or the Rung Sat Special Zone doing recon and springing ambushes, and training ARVN commandos. They were extremely effective, but they were new and that seems to have been their normal day-to-day job.
Assassinating and kidnapping would be most common under Operation Phoenix, which SEALs were pretty active in. Again, this could include Green Berets, but SEALs were more common. The SEALs were also pretty active during the Tet offensive and even got into some door to door urban fighting.
Then a step down, you have your Long Range Reconnaissance Patrol, or LRRPs (Lurps) doing things that seemed even hairier at times. The were special units who were part of larger units, like the 101st Airborne. They operated in 6 man teams and were used to look for the enemy before sending in the rest of the troops. They would be dropped off to recon an area and try to stay hidden if they found the enemy. This didn’t happen a lot of times and they could easily find themselves in the middle of a couple thousand Vietnamese wondering how they were ever going to make it out. I’ve read of one where they were dropped in the middle of thousands of enemy that were amassing for a base assault, and another where a mine shredded the team and alerted the enemy to their presence. 6 guys who were severely wounded still managed to fight off hundreds of enemy.
So, that may not be any specific help, but you can probably google MACV-SOG, the Rung Sat Special Zone or LRRPs and find out details of some specifics missions that took place tht might be worth working into a game scenario.
