How about:

  function convertToMilitary(value) {
    var time_regex = /(\d{1,2})(?:[: ]?(\d{2}))? *([APap][Mm])/;
    var match = time_regex.exec(value);

    if (match != null) {
        var hour = parseInt(match[1]);
        var minute = parseInt(match[2]);
        var period = match[3].toUpperCase();

        if (period == "PM" && hour < 12) {
            hour += 12;
        }
        else if (period == "AM" && hour == 12) {
            hour = 0;
        }

        if (isNaN(minute)) {
            minute = 0;
        }

        minute = "00" + minute.toString();
        hour = "00" + hour.toString();

        return hour.substring(hour.length - 2) + minute.substring(minute.length - 2);
    }
    else {
        return null;
    }
  }

Yes, but your code doesn't take that into account. The switch, as written, treats 1 AM and 1 PM the same, making both 1300.

Here is correct function:

function timeStandardToMilitary(time){
    return time.replace(/(\d{1,2})\s*:?\s*(\d{1,2})?\s*(am|pm)/gi, function(string, hour, minute, suffix){
        minute = minute || '00';
        return (+hour + 11)%((suffix.toLowerCase() == 'am') ? 12 : 24)+1+':'+((minute.length === 1) ? minute+'0' : minute);
    });
}
