Getting stuck a little, and trying to grind themselves out of it, rather than calling for the HQ company M88 VTRs or at least a couple of other tanks from their own platoon [2nd platoon, Bravo Company] to hook on the tow cables before they'd made it worse.
I'd say two other things are likely, too: that probably happened at night, and they waited until daylight to commence recovery operations for safety's sake, and the boss in Bravo 26 is not happy with somebody.
Could be worse.
