Once again my help is needed 
We don't play games, we declare war 
In brief, the Blitzkrieg strategy included the following
features:
1 -Combine land and air assaults to maximise destruction to enemy
positions.
2 -Use paratroopers to secure important positions behind enemy
lines.
3 -Strike fortifications hard and decisively with artillery, air
raids or paratrooper assaults: whichever is most appropriate to the
location.
4 -Strike quickly and decisively on land using mechanised
divisions.
5 -Support mechanised assault with close air support from fighter
bombers.
6 -Draw enemy attention to areas through feigning assaults in
areas: thus reducing resistance in the primary intended area of
assault.
7 -Assaults to work in pincer movements, encircling enemy forces
and forcing subjugation due to lack of supplies.
