</Defs>

copy this. Change what you want. just don't change thingclass. and save your Def folder.

if you don't need 22 or 33 or 4*4, delete it.

2. add comp+@ in patch file

<?xml version="1.0" encoding="UTF-8"?>
<Patch>
  
  <Operation Class="PatchOperationFindMod">
	<mods>
		<li>Ground Turret Mod</li>
	</mods>
	<match Class="PatchOperationSequence">
		<success>Always</success>
		<operations>
			<li Class="PatchOperationAdd">
				<xpath>Defs/ThingDef[defName="yourturretnameone"]/comps</xpath>
			<value>
				<li Class="FP_GTM.CompProperties_FP_GTM_B">
				<Customhatch>GTM_Hatchqwer</Customhatch> <!-- input your own Hatch's Defname! -->
				</li>
			</value>
			</li>
			<li Class="PatchOperationAdd">
				<xpath>Defs/ThingDef[defName="yourturretnametwo"]/comps</xpath>
			<value>
				<li Class="FP_GTM.CompProperties_FP_GTM_B"/> <!-- no custom hatch -->
			</value>
			</li>
			
		</operations>
	</match>
  </Operation>

</Patch>
