NIACT & Army Culture
For many sailors, NIACT will be their first exposure to Army culture. Every service has a distinct culture, which makes for a never ending source for inter-service humor. However, what's funny from a distance might seem less so close up. Sailors should expect to experience some of the same culture-shock that they might have encountered when visiting other countries. The same wisdom that applies when visiting a host country also applies to operating with another host service: be respectful, assume that their methods for doing things is based on best practices, learn what they have to teach by listening but do speak up if you believe there is an unacceptable safety risk. Finally, consider that the Army staff has heard every possible comparison (favorable or not) to how the Navy does things. Respect that your instructor has a job to do and it's not your job to change Army practices. Keep in mind, your Army instructors have the challenge of delivering to Navy personnel of all grades training which in their culture is a basic entry requirement for new recruits. Other differences that you will experience include: different standards for billeting based on rank, increased emphasis on physical fitness (you will PT), and different courtesies.
NIACT & Navy Leadership
Although groups going through NIACT are made up of IAs that are pulled together from many different parent commands, they represent the Navy as a whole and must function as a team while at NIACT. Based on this, Navy leadership issues associated with an ad-hoc command can be prevented with more pro-active leadership from senior enlisted and officers on site. To this end, if you are a senior enlisted or a junior officer, be prepared to act as a group leader ensuring professional conduct at NIACT. Army culture is such that senior enlisted personnel are typically designated as platoon leaders. Navy officers therefore need to act in a supporting role for the senior enlisted personnel designated in the command structure established by the Army.
