I was a sailor for a short and I am thinking of writing a few wordplay on the services.
The Army is first.
P is for pupil of learning military ways
R is for rest and recreation when jobs complete
I is for individual workers
V is for variety of jobs
A is for active
T is for teammate
E is for enunciating words the Army way!
There is a regular Army private as well as a Private First Class. The next few levels from Corporal to the various ranks to General will follow.
