> symbol on sides of tanks.

I always wonder about this when I see US or Israeli tanks on TV. What does this mark “>” on their side mean? Sometimes its pointing up.

Thanks

The chevron on military vehicles is an anti-fratricide measure. The orientation and anyother symbology or numerics within the chevron is a code describing which specific unit that vehicle belongs to. http://www.globalsecurity.org/military/library/policy/army/fm/71-3/f377aph1.htm This gives some explanation.
