The reasons we join:

Steady paycheck
Guaranteed employment
Sick benefits after service
Get to shoot guns

Morality or political ideology are not primary motivators for most dudes that join.

Its mostly young men from the lower ladders of the wealth and privilege hierarchy.

We are basically mercenaries. You will only find loyalty in the lifers and the officers.
Rank and file don't give a shit except what benefits them and their bros.
