One Army Concept
Saladin reminds us it's very simple. The rules are:
1. The default setting for all situations involving the TA is "Casual Labour, you are not entitled."
2. Apply the "One Army Concept" only if the MOD will benefit from the deal.
3. If Rule 2 applies but the soldier also derives some benefit add some caveat to remove that benefit.
And remember folks, it's a concept, not reality...
