Nothing is wrong. It is the same page, there is only one. Each time a new round starts, the picture is replaced with a new one. Sherman just puts the link every time for convenience.
the picture is an M551A1 Sheridan light airborne tank, armed with a 152 mm gun tuge that can fire shells or launch missiles and a small upper "turretette" with a 50 caliber machine gun for AP use
Ansawer should include-
A)The weapons designation(as in "M-16", "F-15", "M1A2" and so on...)
B)The weapons classification(Fighter, MBT, HMG and so on)
C)The weapons weapons origin country(you dont really need clearefication, do you?!)
