The picture show that the soldier from Pakistan Army capture picture during Parachute Jump. It’s very difficult task but Pak Army soldiers fulfill these task very easily because their training is very tough, and during training they learn many difficult task including air borne tasks and activities too. This is probably para training in Para school of Pakistan Army.
The soldier is smiling while looking into the camera and parachute is open. We can see another parachute in the background too and many others probably down on near the ground.
