A military term for an operation in a situation where ROTC cadets are deployed into a combat situation.
The ROTC cadets are separated into two platoons; the first being the dedicated cadets who wish to better themselves in their training to become military officers, the second being the 'shammers' i.e. the people who do not care to better themselves or to be an officer and only go through an ROTC to have their schooling paid for.
The operation consists of the platoon of dedicated cadets shielding themselves in combat with the disgusting, fat bodies of the undedicated cadets. The reason for this being that the undedicated cadets are useful for only taking bullets.
These indifferent cadets will assist in Operation: Shammer Shield by running out into the clearing and revealing the location of the machine gun nest.
