Final answer:
The specific time to complete Initial Military Training (IMT) was not directly provided, but information indicates increased training commitments for soldiers. Changes in military requirements post-Iraq War include intensified training, with the Army considering an increase of annual drill requirements from two to up to seven weeks per year for National Guard and Reserve soldiers.
Step-by-step explanation:
The specific time Soldiers have to complete Initial Military Training (IMT) before moving to the sustaining phase is not directly mentioned. Nonetheless, the available information suggests that the training schedules for soldiers, including those in the Army's National Guard and Reserve components, have become more demanding post-Iraq War era. Traditionally known for the "One weekend a month, two weeks a year" training commitment, changes over time, particularly post-9/11 conflicts, have led to increased activation and deployment of reserve component soldiers, pushing the necessity for more intensive and frequent training regimens.
According to the data provided which references the situation as of July 2012, the Army's top general stated intentions to increase annual drill requirement from the standard two weeks per year to up to seven weeks per year, indicating a significant increase in training obligations. While this information does not directly answer the original question regarding the length of IMT, it highlights the increased commitment expected from today's servicemembers compared to past expectations, especially within the context of the Reserve and National Guard roles.
