My in-laws are planning to apply for B2 visitor visa. My father in law had worked in military as Havildar 20 years ago and he got basic weapon training. So do I need to put yes in the below DS 160 question?
Do you have any specialized skills or training, such as firearms, explosives, nuclear, biological, or chemical experience?
Is there any advantage or disadvantage for putting yes here?
