Annual shotgun proficiency training must include a minimum of rounds of duty ammunition fired at a range of at least 15 yards.

5 rounds

Explanation:

According to my research on police training requirements, I can say that based on the information provided within the question training must include a minimum of 5 rounds of duty ammunition fired at a range of at least 15 yards. This is so that law enforcement officers are acquainted with the weapon and are prepared for its use if necessary.

I hope this answered your question. If you have any more questions feel free to ask away at .

if interdependence implies a two-way dependence, and if each partner is equally dependent on the other for success, then there is an equal commitment to the making the partnership successful. the advantage is sustainability of the relationship, the disadvantage is that decisions are "democratic" and therefore may take longer to reach and more likely to be a compromise (which is not always the best solution). as the interdependence moves away from equality, the decisions become more influenced by the more independent partner. in the extreme the relationship becomes more dictatorial and more like "master-slave". generally the relationship has less commitment in both directions and is more likely to be temporary.

if one generalizes (and one shouldn't), equity partnerships, which is probably what is implied by interdependence, can be slow to progress or change but durable. the extreme alternative, independent-dependent partnerships tend to be efficient but more fragile.

hope this but you will have to site your own evidence. : )
