My d's best friend goes to University of North Florida. She came in as a freshman in the fall with 6 hours of AP credit. She's being told that she must do all 9 hours of the summer requirement because they do not accept partial AP credit below 9 hours..
With a ground clearance of 48 cm (18 in.), the Abrams tank can climb over obstacles that are 1.07 meters (3.5 feet.) high and 2.74 meters (9 feet) wide. They can ford rivers up to 1.22 meters (4 feet) deep without preparation , and up to 1.98 meters (6.5 feet) deep with the use of a fording kit. The new T-158 tank track has a longer life span than earlier track, and the removable rubber pads make it more cost effective.
Out of this number approximately 1 000 out-dated M1 main battle tanks were upgraded to the M1A2 standard. It is planned that this tank will remain in service beyond 2050. The M1A2 has been exported to Kuwait (218) and Saudi Arabia (457). The Abrams is protected by Chobham composite armor.
