Maybe the remaining forces attack in waves. Since they want to throw anything at you a soon as possible to prevent you from moving inland. Your team holds off the first wave when reinforcements come, lots of US soldiers, and you're sent to follow/capture/kill Guba. Sneak back to the shore and flank enemy lines. Try to not attract to much attention, most easties will be moving on the westies landing anyways.
Find Guba and have multiple endings.
1.) capture = kill everyone around him and your officer shoots him in the foot and he falls as he runs away, but you catch him and go back to your lines.... something like that....
2.) Follow = maybe Guba is going somewhere, kill the pilots of another Mi24 and follow Guba's mi24 to somewhere else to either kill/capture/reveal where abouts to command....
little sketchy on that idea....
3.) Kill = as Guba's heli (mi17,mi24, or even stolen uh60, whatever) takes off, this is a cutscene, SHeplan comes up sets up the LAW or Carl Gustav and movie style, shoots the rocket. Camera follows rocket slow mo then cuts to inside cockpit slow mo as rocket speeds towards the heli....
BOOM and into the water to hide the nasty looking OFP heli wreck. MAybe at a port or something.
My favorite idea...
Requires some handy camera skills though.
