I have found a source that references the type of howitzer. The bad news is they don't tell us and it probably will not be made public.

The operative info: "The official declined to say whether the U.S. is sending its M777 or M198 155mm howitzers. Both American cannons are a different caliber than Ukraine’s 152mm Msta-B howitzers, but they share the same “basic outlines,” a defense official said Monday."

I hope they are M777s, as they are much easier to move. The Ukraine is also getting some PzH 2000 howitzers from the Dutch. How many I don't know. https://www.armyrecognition.com/defense_...ition.html

These weapons will take significantly more training. However, they are extremely effective. The have a very high rate of fire compared to the M777 and similar, at least in bursts. They can also move by themselves and do not have to be "emplaced" to fire. If the Ukraine could actually get 100 or so of these in the near term, it would potentially be a war-winner. Troops and armor of a BTG in the open won't last long if even one of these is available and in range. Bad news is they can eat up ammunition at a very high rate.

UPDATE:

This confirms they are M777 howitzers. These howitzers are much more mobile than older models, even though they are towed cannons. They can be set up quickly and moved quickly. Ukraine hasn't commented on Russian counter-battery fire, but being able to move quickly is a big plus.
