Enough. These kinds of modifications may make sense on some practical level, but they are in no way authorized in service trim. The whole "commander's discretion" schtick tells me that the OP is still fairly junior, and working on the forgiveness/permission principle while he waits for his unit leadership to catch up with him. If the unit structure and mission called for these kinds of upgrades, they would be taking place in an arm's room under qualified hands at government expense. Don't mean to be a killjoy, but this just isn't how the Army works.
