Sir as far as my concern it is possible to apply but difficult to get PR ...is it so ? Because job experience must be of relavent trade not different .Please clear my doubt if you have idea about that.
It isn't the case.
Unless make a mess on your documents, your application will cruise.
Be it a military personnel/trade/software person, they all should be gone through same process and security screening.
The delay in the processing time vastly inclines to number of trips outside your country(more security screen) and complexity of your case.
That being said, that wouldn't deter you to get PPR but create a simple delay.
I believe we all can wait with patience if we are serious about our Canadian dream

All the best
