Can you identify these unit crests?

I bought these at a estate sale and can't find them in my book!

[JBFloyd]

The fourth one is the 79th Field Artillery Regiment (240mm Howitzer)(Motorized).

[JBFloyd]

The first one (Golpeo Rapidamente) is the 124th Cavalry Regiment (Special).

[VerKuilen Ager]

Golpeo Rapidamente (I Strike Rapidly) - 124th Cavalry/124th Mechanized Cavalry Recon Squadron/124th Cavalry Regt.

Mobilitate Vigemus (Our Strength Is In Mobility) - Army General's School/ Ground General's School/Cavalry School.

Clip Their Wings - 601st AAA Gun Bn./601st Coast Artillery Regt.

The different i.d.s represent the various redesignations the unit has gone through. An examination of the size, fastener and maker's mark can sometimes indicate which era the item belongs in and suggest which designation is approprite for the specific item. For example, a 601st with clutch fastener with 9m Meyer mark would not be a 601st CA, while a Meyer marked example (no M-number) with screwback might be.
