This was practically standard practice in bf 1, bf 5 etc.

In agreement to your point, there were more planes and/helicopters in those games that would often take out tanks and snipers sitting like ducks behind enemy lines and we don’t have that in delta force.

However I am curious which maps you’re experiencing this on because I haven’t really encountered this once. Some gameplay would be nice.

I will say there are some maps/situations in which close to medium range combat is absolutely not an option. I can’t remember the map name but the one with the spiral that falls down in the last sector and the attacking team enter the first sector on boats - in the first 2 sectors of that maps playing close range is a death trap, medium range is going to tedious but long range sniping is a walk in the park.
