The Biden administration has been helping the Ukrainian military prepare for its now ongoing counteroffensive for the last couple of months by fulfilling specific arms requests, an administration official says, writes CNN.

Ukraine had been asking the US for weapons specifically suited to their planned southern counter offensive in the months leading up to the launch this week, the official says.

The US fulfilled many of those requests - including additional ammunition, artillery and Javelins - over the course of several presidential drawdown assistance packages provided to Ukraine over the last two months, the official said.

Those packages have been public knowledge, but it was not known at the time that they were designed in part to supply the now ongoing counteroffensive.
Defense Secretary Lloyd Austin and top US General Mark Milley have routinely talked to their Ukrainian counterparts to determine what specific weapon needs depending on Ukraine’s battlefield goals.
