Rates are reduced by 12 at night. 2 Prepared Defense is based on defender in positions prepared for a minimum of 24 hours. 3 Hasty Defense is based on defender in positions prepared for less than 24 hours. 4 Units cannot sustain these rates for 24 hours. 5 Sustained rates of advance are not possible without a ratio of 3:1, except in very rare instances usually involving complete surprise. 6 Rates of advance greater than 6:1 ratio are between this row and unopposed rates. The following are the factors for tactical surprise: –Complete Surprise rate from table above x5 (example: 1989 OPN Just Cause, 1973 Yom Kippur). –Substantial Surprise rate from table above x3 (example: 1991 OPN Desert Storm, 1967 Israeli attack in Sinai). –Minor Surprise rate from table above x1.3 (example: 1944 OPN Overlord). –Effects of surprise reduce by 13 on day 2, by 23 on day 3 and do not apply on day 4.
