If then statement, multiple conditions, multiple actions using OR

I am having trouble using a fairly simple If then statement using OR. I have attached a sample file. I am simply trying to create a field with the new product group name, based on the old name. Column C is the old product group. Column D is where I want the new product group name to appear. In one statement, I want the formula to spell out:

if C2 is Tools_Service then D2 is TLS OR

if C2 is Software_Service then D2 is SAAS OR

if C2 is Managed_Service then D2 is MSP OR

if C2 is Cloud_Computing then D2 is CLD OR

if C2 is Consulting_Service then D2 is CSLT OR

if C2 is Angel_Funding then D2 is AFD
