Help : can't find the name of a game. ( tip of me tongue etc )

Used to play a game on a PC, a few years back.

you were a machinegunner in a nest. Enemy tanks, paratroopers, APCs, fighter aircraft came at you in waves. you had limited ammo and a few missiles.

There was a night mode where you had to do the same thing with only a flashlight circle to kill the baddies.

the heavier and heavier waves eventually got you.

Anyone know what it was called ? graphics quite old school but addictive

which is why I want it again !
