Khyber Pass - 2017, Afghanistan, Asia.
Palistan forces cross the Pakistan/Afghanistan border at the Khyber Pass to take out ISIS hideouts and training camps following a four day period of ISIS suicide attacks causing over 120 deaths, including military personel and 400 more injured.
The operation begins with artillery preperation which is then followed by infantry entering Afghanistan who take out six ISIS hideouts and two training camps.
I have given the Pakistan forces mountain infantry as that makes sense and also soe air support.
